WebdriverIO has dropped support of sync mode, hence changed to async.
Update npm packages: @wdio/*, wdio-mediawiki
because async mode needs at least @wdio v7.9.
Remove npm packages: @wdio/dot-reporter and @wdio/sync.

The numbering in the content of the test revisions was slightly changed
to fit the data-pos attribute numbering in the revision tags.
Note that this is not completely cleaning up the step_definitions
from the Ruby tests. This will be done in a follow up after all
tests are ported.
