• Major (something is not working as expected)
• Minor (something but could be improved)
• Trivial (documentation needs correcting and other non-functional issues)

Describe the bug

Installations of extensions using the pack can't complete because of buggy extensions. This PR removes them and update the packages with newer improves ones. The PR also removes old node dependencies that were installed in the devcontainer to improve build time.

@gagnonanthony @arnaudbore If any of you can try building the devcontainer and verify that at the end of the build, those two extensions are installed :

• nf-neuro.test-data-treeview (Test Data Treeview)
• nf-neuro.nf-neuro-extensionpack (nf-neuro extension pack)

To check that extension installation has completed, check that :

• there is no more activity from the extensions store (Ctrl+Shift+X)
• there is not much happening in View>Output>Extension Host (Remote), except from an error from KorbinianEckstein.niivue and one undefined

If that's good, approve the PR, and we merge !

From my end, everything seems fine! There aren't any activities in the extensions tab, and nothing other than the NiiVue error in the output!
