QtWebEngine/ChromiumVersions

The Chromium version that is part of each Qt WebEngine version can be determined by:

• Check the CHROMIUM_VERSION file in qtwebengine source root CHROMIUM_VERSION
• Checking out the documentation of the respective Qt Version
• Checking out the default user agent sent to a server
• Running the following shell command inside the git repository while changing the version tag as needed

git show v5.12.0:tools/scripts/version_resolver.py | pcregrep -o1 "chromium_version *= *'(.*)'"

• Using function call qWebEngineChromiumVersion (since 6.2)
• Visiting url 'chrome://qt' (since 6.6)

(Note, the Chromium versions here are just the base versions. Security patches are backported from the most recent Chrome releases, to all supported versions) (Note, that QtWebEngine was first provided in Qt6 with Qt 6.2.0. So there are entries neither for Qt 6.0.x, or for 6.1.x)
