Environment variables that include numbers are not parsed

[JoostGB]

General

• PHP version: 8.1
• Magento version:2.4.5
• Module version: 3.10.1

Issue description

Environment variables that include numbers are not parsed.

Steps to reproduce

1. Load environment variable INCLUDES_NUMBER_1=somevalue
2. Use this for a configuration like: '%env(INCLUDES_NUMBER_1)%'
3. Run setup:upgrade
4. Expected result for the configuration should be somevalue
5. Actual result: %env(INCLUDES_NUMBER_1)% (literal)

Suggested solution

Update the regex in Semaio\ConfigImportExport\Model\Resolver\EnvironmentVariableResolver from '/\%env\((?!PHP_|HTTP_|SERVER_|SCRIPT_|QUERY_|DOCUMENT_)([A-Z\_]{3,})\)\%/' to '/\%env\((?!PHP_|HTTP_|SERVER_|SCRIPT_|QUERY_|DOCUMENT_)([A-Z\_0-9]{3,})\)\%/'

And also create a testcase for this Setup: putenv('INCLUDES_NUMBER_1=testvalue5');

Validate: $this->assertEquals($this->environmentVariableResolver->resolveValue('%env(INCLUDES_NUMBER_1)%'), 'testvalue5');

@JoostGB Good catch! It makes sense to allow numbers, so I've implemented your suggested solution.
