PHP packages upgrade and added support for PHP 8.4

Here's a summary of the changes:
- I updated `composer.json` to set the PHP requirement to `>=8.2`, upgraded `phpunit/phpunit` to `^11.0`, and `squizlabs/php_codesniffer` to `^3.0`.
- I updated `.travis.yml` to ensure testing against PHP 8.2, 8.3, and 8.4.
- I ran `composer update` to refresh the dependencies.
- I used Rector to refactor the code for PHP 8.4 compatibility.
- I addressed any failing tests that arose after the upgrade.
- I ran PHP_CodeSniffer to correct coding style violations.

feat: Migrate CI from Travis CI to GitHub Actions

This commit migrates the continuous integration pipeline from Travis CI to GitHub Actions.

The new GitHub Actions workflow (`.github/workflows/ci.yml`) includes the following features:
- Matrix testing for PHP versions 8.2, 8.3, and 8.4.
- Composer dependency installation and caching.
- Execution of style checks (`composer check-style`).
- Execution of unit tests (`composer tests-ci`).
- Uploading of code coverage reports to Coveralls.

The `.travis.yml` file has been removed.
The `README.md` has been updated to reflect the change to GitHub Actions, including new build status badges.

Note for repository administrators:
For Coveralls integration to work correctly, ensure that `COVERALLS_REPO_TOKEN` is not set as a secret if using `secrets.GITHUB_TOKEN` with the `coverallsapp/github-action`. The official Coveralls GitHub Action recommends using `secrets.GITHUB_TOKEN`.
