Adjust regex rules to allow adding tweets from x.com domain

I've modified the regex check to work with both twitter.com and x.com links. But the issue i that we still don't have a Media oEmbed provider for the x.com. So to properly work with links from the new domain you should create your custom provider using the oEmbed Providers → module or wait for the core's Twitter provider update.

There is also an existing issue to support x.com in providers of oembed.com on Github.

https://github.com/iamcal/oembed/issues/710

And when the X oembed provider will be added to https://oembed.com/providers.json finally, the array in src/Plugin/media/Source/Twitter.php getProviders() function also needs to be changed to include the new X with the same provider_name, otherwise it won't work.

@paulrad, thanks four your MR, I just added a commit, now it seems to work fine.
Btw, X is now in provider list, thanks for your note, @kaszarobert.

p.s. Also added a patch to use with composer for now.

The patch provided in #9 works fine for me.

Now that twitter.com site is being redirected and replaced with x.com, users will expect to embed new content with x.com URLs. Therefore I think this is a pretty important thing to merge this to the module ASAP.

I tested the patch from #9 which works fine. Thanks!
I agree with @kaszarobert that this should be published soon.
