[11.x] Add replaceable tags to translations

[LegendEffects]

Turned #51188 into a PR.

When writing translations there are times when you may want to inline some HTML, such as for bolding some text or placing a link in the middle of a sentence, currently, you can achieve this by doing something along the lines of:

{!! __('Something <b>bold</b>, and a <a href=":href">link</a>', ['href' => 'https://laravel.com']) !!}

But this isn't very nice or readable to a translator, FormatJS already has a solution to this with Tag Replacements, these look like normal HTML tags but they don't support attributes, they can be added with callable:

{!! __(
    'Something <b>bold</b> and a <link>link</link>',
    [
        'link' => fn ($children) => "<a href=\"https://laravel.com\">$children</a>"
    ]
) !!}

This takes the complexity away from the translator (as in the person, not the class), and makes the code more maintainable if you want to modify that anchor tag with a class then you don't have to go through each translation to add it.

This still requires the usage of unescaped echos within blade, I'm happy to accept any ideas for making this into a HTMLString to avoid this but I didn't want to pile too much into this merge.

This change should be fully backwards compatible.

@taylorotwell Is there anything I can do to help get this merged?
