deps: bump promql-parser to 0.9 for limitk grammar

v0.9.0 adds grammar rules for limitk and limit_ratio in the
aggregate_op production. v0.8.0 declared these as `%expect-unused`
tokens but never bound them in the grammar, so `limitk(...)` queries
failed at parse time before this bump.

The bump also widens the token id type from u8 to u16. Updated two
local helper signatures (aggregate_op_name, binary_op_kind) to match.
No behavior change.
