meson: docs: Add {html,man} targets, rename install-doc-*

We have toplevel html, man targets in the autoconf build as well. It'd be odd
to have an 'html' target but have the install target be 'install-doc-html',
thus rename the install targets to match.

This commit of one of its nearby friends appears to have broken crake's docs build:

ERROR: Can't invoke target `html`: ambiguous name.Add target type and/or path:
- ./doc/src/sgml/html:custom
- ./doc/src/sgml/html:alias

See <https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=crake&dt=2023-11-23%2012%3A52%3A04>

cheers
