add some Workflows (Pester, PSScriptAnalyzer)

[T0biii]

• dependabot for dependency updates for the actions
• PSScriptAnalyzer
• Pester as we got now .test files

the Pester worklow gets red if something with Pester fails
and maybe @joakimbergros got a Pester config for us?

e.g. for code scanning:
https://github.com/T0biiias/Modules.QRCodeGenerator/security/code-scanning
after merge:
https://github.com/TobiasPSP/Modules.QRCodeGenerator/security/code-scanning

we can still discuss what should be set here:
https://github.com/TobiasPSP/Modules.QRCodeGenerator/pull/24/files#diff-13c6613fa5775bc9c8a11734f08caf959197561760e0bbd87eafad1adcee3f4dR39

We could put an config.pester.psd1 file in the root so it can be used by both local testing as well as the workflows.

Something like

@{
    Run = @{
        Path = '.'
    }
    CodeCoverage = @{
        Enabled = $true
    }
    TestResult = @{
        Enabled = $true
    }
}

Then we could load that file with Import-PowerShellDataFile and cast it to a PesterConfiguration object.

Let me know if this sounds good so I can create the file and adjust the tests.

Sounds good to me
I checked: "If checked, users with write access to TobiasPSP/Modules.QRCodeGenerator can add new commits to your add-workflows branch."
so you can directly commit on my branch https://github.com/T0biii/Modules.QRCodeGenerator/tree/add-workflows

I did some restructuring for the script analyzer to be happy, let me know what you think.
