chore(docs): fixing documentation

[m1ga]

While creating a new update for DefinetlyTyped I found some issues:

1. Fixing the generator: update typescript docgen docs-devkit#262
2. Fixing two places in the docs (this PR)

It looks like the generator has special cases for the three events ('addEventListener', 'removeEventListener', 'fireEvent') and outputs them twice when you put them in the exclude part.

This PR will add remove them from the exclude part (not 100% correct but the tests will pass, have to adjust that in the future).

Errors from the DefinetlyTyped test tool that are fix with this PR:
