Add concurrency cancellation to PR-triggered workflows missing it

[mukeshpanchal27]

Description

Several workflows cancel superseded runs via a concurrency group (js-lint, php-lint, php-test-plugins, plugin-check, codeql, props-bot). The following do not, so pushing multiple times to a PR runs duplicate jobs to completion:

• .github/workflows/e2e-test.yml
• .github/workflows/spell-check.yml
• .github/workflows/add-pr-labels.yml

Impact

Wasted Actions minutes and slower feedback when a PR is updated in quick succession.

Proposed fix

Add the same block already used elsewhere in the repo:

concurrency:
  group: ${{ github.workflow }}-${{ github.event_name == 'pull_request' && github.head_ref || github.ref }}
  cancel-in-progress: true

Location

• .github/workflows/e2e-test.yml
• .github/workflows/spell-check.yml
• .github/workflows/add-pr-labels.yml

Acceptance criteria

• Each workflow above has a concurrency group with cancel-in-progress: true.
• Superseded PR runs are cancelled when a new commit is pushed.
