Update links to the rpy2 source

[timokau]

If I search for rpy2 on google right now, the first three links I get are

• https://rpy2.readthedocs.io/en/latest/
• https://pypi.org/project/rpy2/
• https://rpy2.bitbucket.io/

The first two still link to the bitbucket repository. The third is the bitbucket repository itself. It might be helpful to update those links and add a move notice to the rpy2 repository.

This is similar to #261 from the previous move.

Thanks. I had missed the second one (the URL is fixed in master but wasn't in the branch v3.2.x.

For readthedoc, I have considered just deleting all pages but so far thought that they might be missed by people still using an older rpy2 release.

Thanks for fixing the pypi one already. Is there a reason you're not using readthedoc anymore for recent releases?

[lgautier]

Building the doc requires, R and additional packages, and compile a C extension (optional now). This couldn't be achieved on readthedoc.

[timokau]

Ah, makes sense. That's a shame.

[lgautier]

I deleted the bitbucket page. I will look at at whether I can upload built doc to readthedoc.

I also deleted the readthedoc page (all versions there are completely outdated)

Thank you!
