Description

We may need to regenerate older docs to include new changes, e.g. the new version dropdown feature.

Since we need to regenerate the docs for the first time, it would be great if we could encapsulate this in a script. After applying the patch archery docker run ubuntu-docs should do the rest, similarly like we use in the post-release task https://github.com/apache/arrow/blob/master/dev/release/post-09-docs.sh

```
dev/release/generate-docs.sh <version> <patch>

dev/release/generate-docs.sh 6.0.0 # no patch required
dev/release/generate-docs.sh 5.0.0 docs.patch
dev/release/generate-docs.sh 4.0.0 docs.patch
dev/release/generate-docs.sh 3.0.0 docs.patch

1. then deploy to asf-site
   ```
