Fix missing commits & misc.

[ArshansGithub]

Hey! Thanks for developing such a useful extension. I came across an issue at competition where when using this extension, changes were only being staged and not commited. Taking a look today, I noticed that the commit message wasn't being passed in properly

I also simplified some of the git command (using -a flag)

Before:
git add -A
git commit -m "Update at "3/31/2024, 11:39:22 AM""

After:
git commit -a -m "Deploy at \"3/31/2024, 11:39:22 AM\""

I also changed the message from update to deploy since the code is only 'updated' per each deploy rather than using the word 'update'. I feel like the word 'update' would make more sense if it was per save of file but since this automatically commits on deploy it makes more sense to use 'deploy'. Just my opinion though.

Hello just bumping this PR since the entire extension is essentially broken and doesn't do what its supposed to do :(
