docs: update section around testing

chore(helm-chart): bump to 1.0.5

Update collaboration.md

I updated the CodeTogether description to include some enhancements that we just shipped in CodeTogether 4.2. I also added a bit more detail to the feature list and provided some hyperlinks in a couple of places where people would likely appreciate more detail. 

I made no changes to the other sections.

chore(deps): update dependency @types/ws to v8

iPad docs: add copy & paste known issue

We've had two patches to the helm-chart since the last time we bumped the Chart
version.

- https://github.com/cdr/code-server/commit/1ffca5751c36235af686d13c788c8ace5bb0a117
- https://github.com/cdr/code-server/commit/5a36627aae7d8772f4190453dc8aae5da7e73104

This version bump ensures that chart version has the correct date.
