Update docs versions.json

[thisisnic]

The R docs versions.json file was not updated during the release - this PR adds the changes which the release script should have generated.

Note that the other old version docs are in x.y directories (e.g. 6.0) but the last release is 7.0.0: https://github.com/apache/arrow-site/tree/asf-site/docs/7.0.0

So we need to git mv docs/7.0.0 docs/7.0 for this to not have broken links (and we probably need to fix the script that puts it there for the future).

Yes, good catch, just renamed those. So that's another thing to fix in the release script

Do we have a JIRA yet for that?

[jorisvandenbossche]

I was looking for a mistake in the PR I made for this (apache/arrow#12355), but so it's actually how you invoke the script, and that is currently not in the Arrow source code, but in the confluence wiki (we should maybe consider to move that to our development docs)

[nealrichardson]

I can't verify the version.json changes because I think a URL is hard-coded to the arrow site, but the change looks right.

[nealrichardson]

Confirmed that the deploy looks good

It seems that we should have removed patch version from previous_version here: https://github.com/apache/arrow/pull/12355/files#diff-ae6e7dcbd5646d2ecbed30d2c82bec3c6e8bb47271280aa1795f7a3455172e7dR84

   mv docs_temp docs/$(echo ${previous_version} | sed -e 's/^\([0-9]*\.[0-9]*\)\..*$/\1/')

We can remove the .0 in the script, but that's the only thing it is used for, so we could also document to use the script with passing it the shorter name (although handling it in the script will probably be more robust to avoid exactly what we had here ;))
