Update lerna to version independent for the components

With this each component will be updated accordingly respecting major,
minor and patch. The traceviewer-libs that were added as git subtree
have different versions than the vscode-trace-extension components.
Using independent version they will increase according to their current
version.

 Finally, push the branch to the main repository (not a fork!) and use it to create a PR. When the PR is merged, a GitHub release should be created with auto-generated release notes, as well as a git tag. Then the `publish-*` CI jobs should trigger, and if everything goes well, publish the new version of the extension to both registries.
