docs: Use @ref instead of @xref
The @xref command is meant to be used at the beginning of a sentence because its expansion creates a "See " prefix on all output formats, and on older makeinfo versions is strict about enforcing a "." or "," after the command. The @ref command has no such restriction and is just the link, which allows more control over output. This also fixes an issue where there was a repeated "see" in the output.
