PR: Make final clarifications to menu UI text

[CAM-Gerlach]

Description of Changes

• Wrote at least one-line docstrings (for any new functions)
• Added unit test(s) covering the changes (if testable)

• Included a screenshot or animation (if affecting the UI, see Licecap)

Final followup to #24673 , tweaking a few final UI text labels in the menus:

• Rename the View menu to Window in the UI, as its contents generally affect the entire window rather than the view of specific items, is in line with other applications and guidance, and befits its position to the left of Help. For backward compatibility with other plugins, we don't rename the machine-readable APIs referring to it and add explanatory text instead
• Fix "Fix indentation" command has misleading name #5565 , clarifying the name and description of the Fix indentation menu item to make clear what it actually does is convert tabs to spaces for indentation
• Rename "Spyder support" to "Spyder Google group" to clarify what it actually points to
