Fix new JS verification errors and force specific TSC version

The new TSC compiler does stricter checking on the JS documentation
strings. All documentation strings have been updated to pass with
the current version (7.0.2)

In addition, the version of the TSC compiler used during the github
action will be fixed to 7.0.2, so that we don't get these type of
sudden errors again in the future. Unfortunately this means we need
to periodically update this manually.
