What it does

closes #12027

Adds the enabled field to SourceControlInputBox according to the vs code api

also added some semicolons where they were missing

How to test

small extension for testing:

• download here: sourcecontrolinputbox-enabled-test-0.0.1.zip
• build here: https://github.com/jonah-iden/sourcecontrolinputbox-enabled-test

steps for testing

1. remove "@Theia/git" from examples/{browser or election}/package.json
2. build and start theia (browser or electron)
3. download or build and install vsix extension

@jonah-iden in case you weren't aware we can auto-close issues (on merge) if we use the proper keywords in the pull-request description. I updated the description so that it is automatically linked, but it looks like you modified it again afterwards.

thanks for the heads-up about the keywords. Didn't knew about that. I will keep that in mind for future PRs.
Also since i don't have write access rights yet i'm not able to merge PRs, so someone else needs to do that
