refactor: remove redundant acceptance-tests workflow and fix webdriver workflow

Changes:
- Disabled acceptance-tests.yml (renamed to .disabled)
  - This workflow only ran WebDriverIO tests in Docker
  - These same tests are already run by webdriver.yml natively
  - Docker overhead not needed for these tests

- Fixed webdriver.yml:
  - Removed duplicate PHP server start (was started twice)
  - Changed grep from @webdriver to @webdriverio for clarity
  - Added SELENIUM env vars to acceptance tests step
  - Tests now run more efficiently without Docker

Rationale:
- webdriver.yml runs WebDriver helper unit tests + WebDriverIO acceptance tests
- No need to duplicate the same acceptance tests in Docker
- Reduces CI time and complexity
