Subject: [PATCH] Revert "feat: add build sha to parser.c header comment"
 (#4475)

This reverts commit dc4e232e6e83b67065fd54b7a85db0d6081ef224.

Reason: The sha in the generated output (which most distro builds of
tree-sitter, including `cargo install`, strip) produces too many
conflicts when verifying via CI that parsers are regenerated on every
grammar change.

(cherry picked from commit e7f9160867ea1aa639417cd9a491ce4fa162263a)
