When using the git extension, the intent is clear when clicking on "+ Create new branch..." and immediately being prompted "Please provide a branch name". But, when clicking on "+ Create a new branch from..." the intent is ambiguous, since the statement "Please provide a branch name" could refer to the branch from which you wish to base the new branch on or the name of the new branch, the latter being what actually happens.

By specifying "Please provide a *new* branch name...", the intent is clear: the prompt is asking for the name you wish to call the new branch.

Implements many API review changes
Fixes #89558

**Problem**
All of our extensions currently are built using the dom typings. This can lead to runtime errors if you mistakenly use `window` or similar

**Fix**
Exclude the dom typings from compile. Then explicitly import the node types for `URL` and `TextEncoder`

Cleans up API and removes some unused features (e.g. paging)
Adds date formatting
Adds loading progress and message
Removes lots of console.logs 😁
Adds titles to diffs
