Remove activeTab permission request

[SabreCat]

We received this notice from the Chrome Web Store:

On a search, the critique looks accurate--while we use storage in various places, the only place activeTab appears is in the manifest.json. This PR removes the permission request from the manifest.

From my testing on Firefox 105.0.1 (64-bit) appears to be have been working.
The only issue is the version is not updated in the extensions or Readme file. (Had to do a lot of double checking to make sure we have the right one)

Tested:

• Auto connect via the option at the top
• Retrieving messages from a guild/tavern
• Updated while chat is open
• add a message in a guild
• liking a message
• removing a like
• reporting a message
• checking info of a player
• Quick reply on name and avatar

• Keyboard shortcut of ctrl-Enter works

All tested on default options but did open up on large text no avatar to confirm these options work too.
