[docs] Update Bun integration docs for first-party Aspire.Hosting.JavaScript support

[IEvangelist]

Supersedes #1153.

This replacement targets
elease/13.5 because the original
elease/13.4 base branch no longer exists on microsoft/aspire.dev.

Documents changes from microsoft/aspire#17700 (@aspire-repo-bot[bot])

Targeting release/13.4 based on the source PR milestone 13.4.x.

Why this PR is needed

Aspire 13.4 promotes Bun hosting to a first-party integration (BunAppResource) in the Aspire.Hosting.JavaScript package. The existing integrations/frameworks/bun-apps.mdx page still referenced the deprecated CommunityToolkit.Aspire.Hosting.Bun package. The integrations/frameworks/javascript.mdx resource-type list was also missing BunAppResource.

What changed

• bun-apps.mdx: Removed the Community Toolkit badge and Community Toolkit package reference. Updated the install command to Aspire.Hosting.JavaScript. Added an Aside note directing readers who are on Aspire < 13.4 to the Community Toolkit and those on 13.4+ to the official package. Added TypeScript AppHost (addBunApp) examples alongside the existing C# examples. Updated "See also" links to point to Aspire.Hosting.JavaScript NuGet and the JavaScript hosting reference page.
• javascript.mdx: Added BunAppResource (added with AddBunApp / addBunApp) to the integration's resource-type list, with a cross-link to the Bun integration page.

Files modified

• src/frontend/src/content/docs/integrations/frameworks/bun-apps.mdx — updated
• src/frontend/src/content/docs/integrations/frameworks/javascript.mdx — updated

⚠️ CI Failure: Forbidden word detected — "app host"

The Check forbidden words CI check is failing because the PR contains the phrase "app host" (with a space), which is not allowed:

Forbidden phrase (/\bapp host\b/): Use "AppHost" instead of "app host".

This failure is due to content introduced by this PR. Please update all occurrences of "app host" to "AppHost" in the changed files.

CI has been retriggered multiple times and is still failing on the current PR head. This looks likely to be caused by changes in this PR rather than transient infra flakiness.

CI Failure: Forbidden Word

The Forbidden Words check is failing due to a linting rule violation in \src/frontend/src/content/docs/integrations/frameworks/bun-apps.mdx\ (line 35):

\Add a Bun application to your app host using the \AddBunApp\ / \�ddBunApp\ extension method:\

The phrase *\�pp host* (lowercase, two words) is forbidden — it must be written as *\AppHost* (PascalCase).

Please update line 35 to use \AppHost\ instead of \�pp host\ to fix this CI failure.

[IEvangelist]

CI has already been retriggered multiple times (latest attempt: 4) and is still failing on Check forbidden words. This appears to be caused by the current PR changes rather than a transient runner issue, so this PR likely needs an update before another rerun.

[docs-from-code automation] repeated CI reruns
We retriggered failed checks multiple times (latest attempt: 13). The failures still appear tied to this PR's current changes, so this PR likely needs code/docs fixes before CI can pass consistently.

[docs-from-code-automation] repeated CI failure note posted

CI has been retriggered multiple times for this PR and the failures continue on the same changeset. This likely needs a PR-side fix rather than another rerun.

[IEvangelist]

We've retriggered CI multiple times (latest run attempt: 17), and it's still failing in Forbidden Words (Check forbidden words). The repeated failure is in the forbidden-words content check, which is typically caused by wording in this PR.

Could someone update this PR to address the failing check directly?
