Handle @stubbed markings from theia API versions

[alvsan09]

Fixes: #34

This change handles @stubbed markings from theia.d.ts versions,
the markings are expected within the boundaries of corresponding 'jsdoc`

This change updates the parser in order to read the special @stubbed marking and
make this information available to the sequence generating the html reports.

How to Test:
Replace grab-theia-versions.ts#THEIA_URL_PATTERN,
to: 'https://raw.githubusercontent.com/alvsan09/test_theia.d.ts/${VERSION}/theia.d.ts'

The above URL points to a repository containing modified theia.d.ts files which are git tagged with versions i.e.
v1.28.0, v1.29.0 and the latest master, the markings are in different places covering Classes, Interfaces, Enums, functions, etc..

• Build the project and generate the reports
• A copy of the resulting filtered-status.html is found at: https://gist.github.com/alvsan09/a329e2a1c91992577d1618e562688f41
• The API marked as stubbed shall be reflected with an orange background and the text stubbed

NOTE: During the testing, it was noted that constructors require a special parsing, so jsdoc's are not directly read and therefore markings as well as documentation hover on constructors are currently not supported.

@alvsan09, based on your approach I've pushed a commit to #36 that checks for @stubbed and marks nodes appropriately. Since merging this PR and then that one would create many conflicts, would you mind giving your feedback on what I've done there?
