DOC: Add note about `git fetch upstream --tags` to contributing guide

[WillAyd]

Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Location of the documentation

https://pandas.pydata.org/pandas-docs/stable/development/contributing_environment.html#

Documentation problem

If you are working from an old fork that doesn't sync tags with pandas upstream, versioneer will install pandas with a really old version tag which other dependencies like pyarrow don't like

Suggested fix for documentation

Add a note that users may want to run git fetch upstream --tags before installing

[MaanavS16]

There already appears to be a note mentioning the need for git fetch upstream --tags
