[Bug] PHP 8.2 and 8.3 breaks the SSL connection to Matomo's database

Nobody has claimed this yet.

**What happened?**
- The config file and certificate work fine for PHP 8.1.
- But as soon as PHP 8.2 or 8.3 are implemented the following error is thrown

[PDOException]
PDO::__construct(): Unable to set local cert chain file `/run/secrets/mysql
/tls.crt'; Check that your cafile/capath settings include details of your certificate and its issuer
See more below.

**What should happen?**
SSL cert should be found when connecting to db with PHP 8.2.

**How can this be reproduced?**
To reproduce the problem:

Update to either PHP to 8.2 or 8.3*
Matomo will fail to connect to the database; it breaks Matomo**
Roll back to PHP 8.1***
Matomo works normally
*PHP 8.2-fpm-alpine or PHP 8.3.8-fpm-alpine
**The error is [PDOException]
PDO::__construct(): Unable to set local cert chain file `/run/secrets/mysql /tls.crt'; Check that your cafile/capath settings include details of your certificate and its issuer
But the config file is fine when using PHP 8.1.
***Php 8.1.15-fpm-alpine

**Matomo version**
5.1.0

Server operating system
https://github.com/matomo-org/docker/blob/master/fpm-alpine/Dockerfile

Computer operating system
Alpine Linux

Start with fpm-alpine/Dockerfile and compare the PHP 8.1.15-fpm-alpine image with the reported PHP 8.2 and 8.3-fpm-alpine versions. Reproduce the PDOException using the stated certificate configuration and inspect how the image and PHP version handle the local certificate chain. Done means Matomo connects to its database over SSL without the certificate error.
