web: the return of pseudolocalization (#7190)

* web: the return of pseudolocalization

The move to lit-locale lost the ability to automagically pseudolocalize the UI, a useful
utility for checking that additions to the UI have been properly cataloged as
translation targets.  This short script (barely 40 lines) digs deep into the lit-localize
toolkit and produces a pretranslated translation bundle in the target format folder.

* Linted, prettied, and commented.
