[Feature request] Add "Signature Help" and toggle comments features

[Riku5543]

Hi there. Nim is my favorite programming language and this extension for Zed is very nice so far, and Zed itself seems to be quite a bit faster than vscode. There's a couple of features missing that stops me from switching over though, so I thought I'd share.

Selecting multiple lines and pressing ctrl + / currently does nothing, but it should toggle whether the lines are commented out or not.

And while typing a proc name, you get to see the documentation for it if it's prefixed with ##, but it currently doesn't show you the proc signature, so it can be difficult to remember what parameters are needed. I'll attach a couple screenshots comparing vscode and Zed.

vscode: typing the proc shows the signature

vscode: starting to write params for the proc shows both the signature and documentation

zed: typing the proc shows the documentation

zed: starting to write the params gives no details

But, the hover has everything needed and is actually really pretty. I just wish it was easier to see that while writing code.
