MySQL: SELECT FOR UPDATE query errors during parsing on all sqlglot versions >= 18.0.0

[SoftwareGuy2020]

Fully reproducible code snippet

from sqlglot import parse_one
query = 'SELECT name FROM temp WHERE name = ? FOR UPDATE'
parsed_sql = parse_one(query, dialect='mysql')

The stacktrace is:

  SELECT name FROM temp WHERE name = ? FOR UPDATE

This does not error on version 17.16.2 and below. Something happened in version 18.0.0 that caused this issue. I verified that the issue is present in all versions above 18.0.0 as well.
