Parser won't properly parse tags that have a similar name

[LucasKovacs]

Describe the bug
The Parser fails to properly parse tags that have a similar name. It seems that the issue is on the regex on Parser::replaceSingle. Maybe it's to greedy and is just trying to replace also tags that are similarly prefixed. In my case I have two similar tags like:

{parser_test}
{parser_test_second}

So when it finds that {parser_test_second} it replaces it ignoring the _second part.

This can be verified with a simple experiment, if I change the order of the tags in the array that I pass to setData, the replacement is properly done, replacing first {parser_test_second} and then {parser_test}

One weird thing to notice, is that is not reproducible 100% of the times, being a few times where, other tags, are properly replaced.

CodeIgniter 4 version
4.0.4

Affected module(s)
Parser

Expected behavior, and steps to reproduce if appropriate
If I pass similar tags to the parser it won't properly parse them.

Situation

$this->parser = \Config\Services::parser();
$this->parser->setData(['parser_test' => 'parser test', 'parser_test_second' => 'parser test second'], 'raw')->render('index.html');

On my index.html I have

{parser_test}
{parser_test_second}

Actual behaviour

Both tags are replaced with

parser test
parser test

Expected behaviour
parser test
parser test second

Context

• OS: [Linux]
• Web server [Apache/2.4.38 (Debian)]
