Robert Griesemer f269d90bf2 spec: use original terminology in metasyntax (cleanup)
The metasyntax used in the spec is exactly the Wirth Syntax
Notation (WSN), which eventually influenced EBNF. Add a link
but keep mentioning EBNF which is likely more commonly known.

Use the original terms in the productions. Specifically, use
the words "Term" and "Factor" rather than "Alternative" and
"Term".

The terminology cleanup also resolves an inconsistency in the
subsequent prose which is referring to the correct "terms" now.

While at it, add a production for the entire Syntax itself,
matching the original WSN definition.

Also, replace the two uses of "grammar" with "syntax" for
consistency ("syntax" is the prevalent term used throughout
the spec).

Fixes #50074.
