Bug: Parser - Replacements happening even if key does not fully matches { value }

Describe the bug If a key of data array contains the start of the next keys, all of the replacements from then on will be done with the value of this first key, even it not fully matched.

CodeIgniter 4 version 4.0.4 (live)

Affected module(s) Parser

Expected behavior, and steps to reproduce if appropriate

$parser = \Config\Services::parser();
$data   = [
    'company' => 'Problem',
    'company_name' => 'X Company',
    'company_street' => 'Street Name',
    'company_city' => 'City Name',
    'company_country' => 'England',
];
$template = '<html> {company_name} <br> {company_street} <br>  {company_city} <br>  {company_country} </html>';
$parser->setData($data);
echo $parser->renderString($template);

Current Output
```
Problem

Problem 
```
What was expected
```
X Company
Street Name
City Name
England
```
Also if the first key on the array is company_c instead of company this will be the output:
```
X Company
Street Name
Problem
Problem
```
