…attributes

`T_STRING` tokens in PHP 8.0+ attributes are either class names or possibly constant names (as a parameter for the class instantiation).
They are never function calls.

This commit ensures that `T_STRING` tokens in attributes are not confused with function calls.

Includes unit test.

Modernize.FunctionCalls.Dirname: prevent false positives on PHP 8.0+ attributes

The `coverallsapp/github-action` action runner has (finally) created a named branch for the 1.x (and the 2.x) series, so let's use that.

Ref: coverallsapp/github-action#100

Grrr....

When PHPUnit has been installed on a high PHP version, some of the dependencies of PHPUnit may now be installed in versions not compatible with PHP 7.4, which would block the install of the Coveralls package.

While this is not (yet) a problem in this repo as the max PHPUnit version is set to PHPUnit 7.x, the issue should still be prevented.

Installing PHP Coveralls globally instead should fix it.

I just wish PHP Coveralls would finally release a version compatible with PHP >  8.0....

Since Composer 2.2, we can be more specific about which platform requirements should be ignored.

This change ensures that only the "high" end of a PHP requirement will be ignored and no other platform requirements are ignored.

As things were, whenever the minimum PHPCS version would be changed, the branch protection settings for both the `stable` and the `develop` branch would need to be updated and all "required builds" referencing the old PHPCS version would need to be removed, while new "required builds" would need to be added referencing the new minimum PHPCS version.

This was a fiddly process and time-consuming.

The change proposed in this commit takes advantage of the Composer `--prefer-lowest` setting to achieve the same without a hard-coded PHPCS version in the build name, which means that once the branch protection settings have been updated for this PR, they shouldn't need updating anymore for future PHPCS version bumps.

This seemingly small change makes a huge difference in performance for this sniff.

On a run of 300+ files, the sniff was more than 7x faster with these tweaks in place.

Universal/DisallowInlineTabs: improve sniff performance

* Add a space-based test case file which shouldn't yield any errors or warnings at all.
* Make sure that the "tabwidth" set for test files is correctly respected.
* Fix the `DisallowInlineTabsUnitTest.5.inc` fixed file.

The `'orig_content'` key only gets set when there are tabs in the token content, so no need for the extra check.
