Update methods visibility in multiple Providers

[attepulkkinen]

This resolves #331

I'm mildly annoyed that some methods are named calculateHolidayName() and some are addHolidayName() and there are even holidayName() but I'm not sure if renaming these would break some backward compatibility somewhere…

I decided against adding tests because this commit doesn't include any logic changes.

Running that command on my computer gives no errors, but I'll write a fix manually.

Also, not sure if this is a known issue, but there is also the following deprecation warning

Detected deprecations in use:
- Rule set "@PER" is deprecated. Use "@PER-CS" instead.

Actually, this is a bit silly style fix. I don't think such type Australia\string actually exists… How do you want to continue?

This seems to be related to friendsofphp/php-cs-fixer version upgrade (v3.46.0 => v3.47.0)

The long-term solution here would be to use enums when support for PHP 8.0 will be eventually dropped.

Thanks for noticing the deprecated ruleset. With recent PHP CS fixer updates I have seen some similar odd changes (and reverted).

Actually, this is a bit silly style fix. I don't think such type Australia\string actually exists… How do you want to continue?

Yes this indeed is a bit silly. Let me see if I can correct all of this. Although not a fan of it (and shouldn't be necessary), perhaps we can pin PHP CS fixer to a specific version.

[stelgenhof]

@attepulkkinen I've made a small (hopefully temporary) change that addresses the latest PHP CS Fixer issues. You may want to rebase your branch and give it another try.

[attepulkkinen]

Thank you. Can you tell when the next version will be released?

[stelgenhof]

@attepulkkinen Apologies for missing your last question. Generally I release a new version if there are a number of valuable changes since the last release. So, at the moment, I don't have any new release scheduled soon.
