Add validRegexPattern assertions

[zlodes]

Why?

1. PHP functions working with regex (preg_match, preg_replace, etc.) work in legacy way — they just return false instead of throwing exception.
2. The way to check if the string is regex is quite hacky, so, would be great to hide the check implementation somewhere.

I see that some tests failed. Fixing. 🤔

@shadowhand Hello mate!

As I can see, the latest release of the package was in 2022. Is there any plans for the next release?

I think there are better regex wrappers that check for failures, such as:

• https://packagist.org/packages/composer/pcre
• https://packagist.org/packages/rawr/t-regx
• and others...

Calling a function with @ suppression is a style I don't want to adopt in this package.

I think there are better regex wrappers that check for failures, such as:

I agree that the current approach doesn't look ideal, but it's the only native way to validate a regex. I'm not sure it's a good idea to introduce additional dependencies into such a lightweight package.

If you're fine with it, I can add equivalent methods using one of the packages you mentioned.

My suggestion for those alternative packages was for your own code, not to be used with this project.
