Release DataFusion 21.1.0

[alamb]

Is your feature request related to a problem or challenge?

During testing of Version 21.0.0 RC1 we discovered that it inadvertently depends both on arrow (and its subcrates) version 34.0.0 as well as arrow-array version 35.0.0

This feature was fixed in #5724 (so datafusion only depends on arrow 34.0.0)

https://lists.apache.org/thread/fnnmrn83spnb2y2l2vdw2v1hd54pfjl7

Describe the solution you'd like

I propose releasing DataFusion 21.1.0 with the fix in #5724

Describe alternatives you've considered

We could do nothing and wait for DataFusion 22.0.0 in a few weeks time.

Thanks @alamb. There is a branch-21 already that we can merge the fix to, and release from there. Note that the release process for DataFusion differs slightly from the Arrow-rs release process (specifically with tags and branches), but hopefully this is documented well enough in dev/release/README, LMK if you have questions.

[alamb]

I have prepared PRs to backport the relevant parts to branch-21:

#5766
#5765

I have created a release candidate here: https://lists.apache.org/thread/qw5067glfmxy4k42wty4vph7pjkgq24p

I am now waiting for the 3 day voting period. Once that has elapsed, assuming no -1 votes, I will release this version to crates.io

[alamb]

The release is approved and available: https://lists.apache.org/thread/tmfzkqnvkmccmy8w2ltpqh0sy4mgy6qq

However, unfortunately I am still working on publishing it to crates.io ((I do not have permissions to https://crates.io/crates/datafusion-execution/21.0.0)

Perhaps @andygrove can help here

I have published the release to crates.io (thank you @andygrove )

Since this release only includes a dependency improvement (rather than any features) I am not planning to publish an update on homebrew.
