Exclude L1TESTs from contributing instructions

[mlubin]

These tests are expensive, currently broken, and aren't covered under CI. New contributors will be confused if they see failing tests, so they should be excluded from the instructions.

- Line 202: Update the rationale sentence in CONTRIBUTING.md that references
`L1TEST`s: replace the word "expensive" with a clear statement that L1TESTs are
excluded because they are currently broken and not run in CI (or similar wording
like "currently broken/not included in CI"), so the rationale matches the PR
reason; ensure the line containing the backticked token `L1TEST`s is changed to
the new wording and keep the tone consistent with surrounding contribution
guidance.
