[Bug]: `--update-snapshots` parse from CLI seems broken

[ogonkov]

Version

1.52.0

Steps to reproduce

run

playwright test --project=chromium --workers=8 --retries=2 --update-snapshots tests/test.e2e.ts:23

Expected behavior

Only selected tests running

Actual behavior

All tests started

Additional context

If i move flag --update-snapshots between two other, like

- playwright test --project=chromium --workers=8 --retries=2 --update-snapshots tests/test.e2e.ts:23
+ playwright test --project=chromium --workers=8 --update-snapshots --retries=2 tests/test.e2e.ts:23

or add explicitly set some value to it, like

- playwright test --project=chromium --workers=8 --retries=2 --update-snapshots tests/test.e2e.ts:23
+ playwright test --project=chromium --workers=8 --retries=2 --update-snapshots=all tests/test.e2e.ts:23

Then only selected tests running.

Looks like that in problematic case tests list is interpreted like value for --update-snapshots, so there is also flag value validation missing.
