Fixed injection of wrong config file

What's Changed

• Create codeql-analysis.yml by @renandelmonico in #2
• Added command to specify phpunit config file by @renandelmonico in #6

Added two commands:

• "phpunit.discoverConfigFile" - if true the extension automatically try to find phpunit.xml or phpunit.xml.dist in you project
• "phpunit.configFile" - path to phpunit.xml or phpunit.xml.dist file. If this config is specified the "phpunit.discoverConfigFile" automatically turns to false
• Updated dev dependencies
