fix: vulnerabilities detected by npm audit

[LoicRiegel]

Problem

When running npm install or npm audit, we get
Found three vulnerabilities (1 low, 1 medium, 1 high)

Fix

So I tried to fix it: I ran npm audit fix from the package's root, from client/ and server/. npm 10.9.2.

I'm not used to working with npm though, so let me know if this was the right way!

Now when you npm install, you get 0 vulnerabilities.

I just launched the extension with VS code debugging, it works. But I couldn't run the test, I'll open another PR for that

This is probably right but I want to look closer at it since so much changed.

Yes of course
