Bug Report Checklist

Description

An internal security tool from the company I am working in, reported potential security breaches and violations of the internal company policies regarding code practices in php-laravel generator.

Those issues were introduced by the initial import of the php-laravel generator (#574) and lately updated in #6346.

• --/src/main/resources/php-laravel/resources/views/welcome.blade.php#L10
  A CSS style sheet for a font included from fonts.googleapis.com
• --/src/main/resources/validator/index.mustache#L204
  A mustache file with the same issue mentioned above.

openapi-generator version

Issue present on master.

Steps to reproduce

None.

Never reported before.

Suggest a fix

Pulling this CSS file does not seem a main feature and creates noises for internal security tools.
Do you see any issue with deleting/commenting them out ?

If you agree on the approach, I can create a PR.
