chore(tests): updated timedMatch test to account v2.9.1 test coverage changes

[petruki]

This pull request focuses on updating the Deno version used across the project and improving the reliability of the TimedMatch test suite. The most significant changes are grouped below.

Deno version upgrades:

• Updated the base Deno image in .devcontainer/Dockerfile from 2.8.1 to 2.9.4 to ensure the development container uses the latest compatible version.
• Updated Deno setup steps and matrix versions in GitHub Actions workflows (.github/workflows/master.yml and .github/workflows/sonar.yml) to use v2.9.4 instead of v2.8.1, ensuring consistency in CI environments. [1] [2] [3]
• Bumped the delay import in tests/deps.ts from @std/async@1.4.0 to @std/async@1.5.0 for up-to-date dependencies.

Test suite reliability improvements:

• Enhanced tests/utils/timed-match.test.ts to introduce a warmUpWorker() function that preps the regex worker before each test, reducing flakiness due to JIT/module-instrumentation costs, especially under coverage runs. Also added a mechanism to track and restore the intended maxTimeLimit for tests.
• Modified test setup (beforeEach) and certain test cases to use setMaxTimeLimit and warmUpWorker, ensuring consistent timing and worker state across tests. [1] [2]
