Suppress PHP warning in CacheClearCommand when is_readable() tries to access dirs outside of open_basedir restrictions

Hey!

I see that this is your first PR. That is great! Welcome!

Symfony has a contribution guide which I suggest you to read.

In short:

• Always add tests
• Keep backward compatibility (see https://symfony.com/bc).
• Bug fixes must be submitted against the lowest maintained branch where they apply (see https://symfony.com/releases)
• Features and deprecations must be submitted against the 7.1 branch.

Review the GitHub status checks of your pull request and try to solve the reported issues. If some tests are failing, try to see if they are failing because of this change.

When two Symfony core team members approve this change, it will be merged and you will become an official Symfony contributor!
If this PR is merged in a lower version branch, it will be merged up to all maintained branches within a few days.

I am going to sit back now and wait for the reviews.

Cheers!

For 5.4, right?

Hi, we're working with 6.4 and I found the bug there, so I worked on the 6.4 branch for this fix. But I just looked into the 5.4 branch and the patch should apply there, too. The line is the same.

Thank you @kopfsalat.
