Inconsistencies in command titles

[gjsjohnmurray]

Type: Bug

1. Some use category while others prefix titles with Git: .
2. Some titles don't use VS Code's word capitalization comvention.

If adopting category consistently I suggest using Git History rather than Git, so it's clearer which extension is contributing the commands.
