Adds a tip to the section on webhook URLs in the incoming webhook
overview and to the section on stream and user IDs in the construct
a narrow documentation. The tip links to relevant articles in the
help center.
Part of work on #19067.
Expands support for the message ID operand for id" operator to be either
a string or an integer. Previously, this operand was always validated as
a string.
Documents narrows now have support for new filters for direct messages:
`is:dm`, `dm`, and `dm-including`. Also documents that `is:private`,
`pm-with` and `group-pm-with` are now legacy aliases for these three
new filters respectively.
Note that API documentation references the help center documentation
for search/narrow filters.
Fixes#24806.
- Updates `.prettierignore` for the new directory.
- Updates any reference to the API documentation directory for
markdown files to be `api_docs/` instead of `zerver/api/`.
- Removes a reference link from `docs/documentation/api.md` that
hasn't referenced anything in the text since commit 0542c60.
- Update rendering of API documentation for new directory.
