doc: Clarify required options for each action in pg_recvlogical.

Each pg_recvlogical action requires specific options. For example,
--slot, --dbname, and --file must be specified with the --start action.
Previously, the documentation did not clearly outline these requirements.

This commit updates the documentation to explicitly state
the necessary options for each action.
