Replace vscode with @types/vscode

[ckipp01]

The main vscode dependency that we use has split up, and it's recommended to instead use @types/vscode and vscode-test. This pr replaces the vscode dependency with @types-vscode. I also update other various dependencies as a few of them were lagging behind which was causing some of the recent updates to not work right.

• Update main vscode dependency
• Update other various dependencies
• Format code with new version of prettier

I did build locally and test installing the latest snapshot of metals, hovers, completions, debugging, and worksheets. Everything seems to be working as expected, but it's best if someone else also pulls this, builds it, and plays around with it, especially since I don't use vscode as my main editor. I'm probably the worst person to do this.

Make sure to thoroughly test this, by publishing a vsix locally and installing it by hand. I’ve tried this in the past and the extension would not activate (i wasn’t able to pinpoint the exact issue), although it was working fine when launching it from the debugger

The relevant code changes are 👍 I’ve left a few minor comments.

However I find the prettier change a bit distracting and out of scope for the PR.
Can we do the prettier 2 upgrade in a separate PR so that we keep this diff on this one more focused?

Sounds good 👍 I was able to do this with no issues.

Addressed the comments and made the changes.

Sure! I undid that update and I'll send in another pr for it.
