Impossible to install in Docker (PHP7 not supported, PHP8 breaking changes)

[PatrykPlewaOfficial]

Bug report

Title

There is a mismatch in the repository between PHP version expected in composer.json and the one installed in Dockerfile.
Running UVDesk is no longer possible on PHP7.4.

However, after selecting the Ubuntu version manually to 20.04 and replacing all PHP packages with any version 8+ it is no longer possible to install UVDesk due to breaking changes in PHP inside the migrations files.

Issue Description

In file /var/www/uvdesk/vendor/doctrine/migrations/lib/Doctrine/Migrations/Configuration/Connection/Loader/ConnectionHelperLoader.php

 public function __construct(?HelperSet $helperSet = null, string $helperName)

the optional parameter $helperSet comes first. Since PHP8 this is no longer possible. This causes the migrations to fail.

Steps to reproduce

Build new image and start the container. Proceed to install in the browser.

Expected result

Successful installation

Actual result

POST wizard/xhr/load/migrations returns

<b>Deprecated</b>:  Optional parameter $helperSet declared before required parameter $helperName is implicitly treated as a required parameter in <b>/var/www/uvdesk/vendor/doctrine/migrations/lib/Doctrine/Migrations/Configuration/Connection/Loader/ConnectionHelperLoader.php</b> on line <b>25</b><br/>[]

Installation is never completed.

Thank you @papnoisanjeev .

When setting up the built-in MySQL DB, there is some issue in `./docker/bash/uvdesk-entrypoint.sh.

mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
Error: Failed to establish a connection with mysql server (localhost)

Secondly, when omitting setting up the DB (no env variables), there is still an issue. In the web browser, the container returns 500 without any specific error message. No errors in the Docker console.
