PHP version numbers need to be strings: If the version `8.0` were
treated as a number, the YAML parser would happily convert it to `8`,
hence dropping the minor version number.
- Move npm tools and config to default places
- Remove now unnecessary config file parameter from npm scripts
- editorconfig and eslint config contradict, adapt editorconfig
- switch JS indent linting to TYPO3 coding standard of 2 spaces
- adapt composer scripts for new npm location
The installed Composer packages will be different depending on the
major TYPO3 version being tested and on the strategy for the
dependencies (highest, lowest). So it makes sense to have
separate Composer caches for these versions in order to avoid
cache misses.
The CI workflow with predefined GitHub actions had an empty `on:`
element, which is invalid. Use the correct event for manually
triggered workflow runs instead.
Composer versions 2.2.0 and 2.2.1 have a bug that breaks PHPUnit.
Until version 2.2.2 is released with a fix, we need to keep to
Composer 2.1 to keep the tests from breaking.
See https://github.com/composer/composer/issues/10387 for details.
