DOC: Add crossrefs to rename_channels docstring

[NatalieNegussie97]

Add See Also section with references to related methods:

• add_proj, del_proj
• set_channel_types, set_meas_date
  This addresses issue DOC: add crossrefs in the info docstring #7774 by adding crossrefs to the 'rename_channels' docstring as requested. The See Also section now includes references to related methods that users might want to use alongside 'rename_channels'.

the diff shows over 3700 lines changed (the entire file). I'm guessing your text editor or IDE did some kind of auto-replacement of spaces/tabs or line endings. Please check

git config --get core.autocrlf

If you're on windows, it should say true; if not then change it:

# run within the folder of your MNE-Python clone
git config core.autocrlf true

If you're on Linux or Mac, it should be input; if not, change it:

git config core.autocrlf input

you can optionally add a --global flag to set it for all projects on your computer.

If that already looked correct, then check your IDE's settings, it might be doing some autocorrection too. Ping us when the diff view of this PR shows only the changes you intended.

Thanks for fixing the line endings! Some feedback:

• You've added the crossrefs here (to the See Also section of mne.Info.rename_channels). The intent was to add the crossrefs to the See Also section of mne.Info itself (here).

• The crossrefs should probably be grouped by function, rather than by object type. For example:

  Add projectors: mne.io.Raw.add_proj, mne.Epochs.add_proj, mne.Evoked.add_proj

  Rename channels: mne.io.Raw.rename_channels, mne.Epochs.rename_channels, mne.Evoked.rename_channels, mne.Info.rename_channels

  ... etc. Hopefully that won't look too messy / be too hard to read. If it does, we can think about alternatives (formatting as a list, putting it in Notes instead of See Also, ...)

• We should probably also add to the end of this warning something like "Check the See Also section for a list of functions/methods that safely modify Info's read-only fields."
