Search for pronouns in field values, names and the bio

[nachtjasmin]

The old approach was refactored. With this PR we are applying all searches to each individual field, including their name and value. This approach is optimized for speed in that regard, that we do the API calls as the last step.

I also embedded a list of all known pronoun.page pronouns, which can be generated using node scripts/generateKnownPronouns.mjs. The current state is commited to the repository and could be regenerated at any time.

A lot of the cases mentioned in #63 are going to be closed with this PR.
