Authenticate Develocity injection integ tests with workload identity (#1112)

## Changes

Follow-up to #1109. That PR left `suite-integ-test-other.yml` on
`DV_SOLUTIONS_ACCESS_KEY`.

`integ-test-inject-develocity.yml` now gets a GitHub OIDC token, in
`solutions.develocity.cloud=<token>` form, from the same pre-step as
#1109. The token goes where the access key went before:

- **`inject-develocity`**: the `DEVELOCITY_ACCESS_KEY` /
`GRADLE_ENTERPRISE_ACCESS_KEY` env var, set per matrix entry through
`$GITHUB_ENV`
- **`inject-develocity-with-access-key`**: the `develocity-access-key`
input
- **`inject-develocity-short-lived-token-failed`**: both env vars and
the input
- **`inject-develocity-with-access-key-from-input-actions`**: the
`DEVELOCITY_ACCESS_KEY` env var

setup-gradle exchanges the OIDC token at `/api/auth/token` the same way
it exchanges an access key. The `DEVELOCITY_ACCESS_KEY` secret is
removed from the reusable workflow. `id-token: write` is granted along
the chain: `ci-integ-test*.yml` → `suite-integ-test-other.yml` → the
jobs. Fork PRs are already skipped for these jobs.

Part of gradle/dv#74660. After this merges, nothing in gradle/actions
uses `DV_SOLUTIONS_ACCESS_KEY`.
