[Python] Provide links to documentation pages for old versions

[asfimport]

Hey folks, apologies if this isn't the right place to raise this.  In poking around the web documentation (for pyarrow specifically), it looks like the auto-generated API docs contain commits past the release of 0.9.0.  For example:

• https://arrow.apache.org/docs/python/generated/pyarrow.Table.html#pyarrow.Table.column

• Contains differences merged here: ARROW-2453: [Python] Improve Table column access #1923

• But latest pypi/conda versions of pyarrow are 0.9.0, which don't include that change.

  Not sure if the docs are auto-built off master somewhere, I couldn't find anything about building docs in the docs itself.  I would guess that you may want some of the usage docs to be published in between releases if they're not about new functionality, but the API reference being out of date can be confusing.  Is it possible to anchor the API docs to the latest released version?  Or even something like how Pandas has a whole bunch of old versions still available? (e.g. https://pandas.pydata.org/pandas-docs/stable/ vs. old versions like http://pandas.pydata.org/pandas-docs/version/0.17.0/)

We could use some assistance with this. I suspect that the docs were updated between 0.9.0 and now when the JavaScript API docs were added to the build. I think this will be less of an issue after we put the 0.10.0 release out (soon)

The published docs are now for the latest released version. I think it would be useful to have an archive of old documentation versions, though. Removing this from the 0.14 Fix Version

I am going to close this as a duplicate of ARROW-13260. And I am working on this (should normally land for the 6.0 release)
