Cannot release DataFusion 36.0.0 to crates.io due to circular dependency

[andygrove]

Describe the bug

It is not possible to publish datafusion-physical-expr to crates.io because it has a dependency on datafusion (datafusion-core), and datafusion-core depends on datafusion-physical-expr.

Caused by:
  failed to select a version for the requirement `datafusion = "^36.0.0"`
  candidate versions found which didn't match: 35.0.0, 34.0.0, 33.0.0, ...
  location searched: crates.io index
  required by package `datafusion-physical-expr v36.0.0 (/home/andy/git/apache/arrow-datafusion/target/package/datafusion-physical-expr-36.0.0)`

The dependency was introduced in #9137

It should be just a dev dependency - I had to add it to get the rustdocs to work. I am unsure how that would affect crates.io deployment but removing it I think would require the removal (or moving ... to where I don't know) of the rustdoc for regexp_like.

As a short-term fix, we can tag the rustdoc with ignore until we figure out a better solution. I have a PR up:
