fix(ci): dedicated shard for IntakeFormCustomPropertyFields; drop non-existent IntakeForm project

Bumping the matrix to 8 with `--shard=X/7` produced 6 idle shards
(shards 3-8 each finished in ~11s with 0 tests) because co-listing
`--project=chromium --project=IntakeFormCustomPropertyFields` under
`--shard` collapses distribution: IntakeFormCustomPropertyFields depends
on the entire chromium project and is `fullyParallel: false`, so
Playwright pins the work to shard 1/N. Same problem showed up in the
previous 5-shard runs as shard 2 timing out at 194 min.

Split the workload so every matrix slot does real work:
- shard 1: DataAssetRules (unchanged)
- shard 2: IntakeFormCustomPropertyFields on its own project
- shards 3-8: `--project=chromium --shard=X/6` (6 chromium shards)

Also drop `--project=IntakeForm` — that project does not exist on 1.13
(only `IntakeFormCustomPropertyFields` was added by #30910); Playwright
was silently accepting the unknown name.
