Replace C# Godot's dependencies with muhammad-sammy.csharp

[manuth]

• I have read the note above about PRs contributing or fixing extensions
• I have tried reaching out to the extension maintainers about publishing this extension to OpenVSX (if not, please create an issue in the extension's repo using this template). (see VSCodium support & availability on open-vsx godotengine/godot-csharp-vscode#12)
• This extension has an OSI-approved OSS license (we don't accept proprietary extensions in this repository)

Description

In a workaround I've created a short time ago, I added the neikeq.godot-csharp-vscode extension.
However, this extension couldn't be published as it depends on extensions which aren't available in the open-vsx store.

Thus, changes made in this PR will change the dependencies to their corresponding open source variants.
In doing so, changes made in this PR will fix the publishing process of the neikeq.godot-csharp-vscode extension.

Awesome! Thank you so much for letting me know 😄

I'll open up a new PR changing all sed-commands to jq as soon as I've got some time left for it!
Thanks for the effort!

I'll open up a new PR changing all sed-commands to jq as soon as I've got some time left for it!

Maybe it would be a nice change, I didn't know previously you could do JSON-writing with jq, so it could be really here.
