Consider replacing qr-code-bundle dependency with the base (non-Symfony) library

Making an attempt at this. Will push shortly.

This does not have to be the approach taken, but I do like that all of these extra dependencies no longer need to be installed. Another consideration here is the compatibility with different versions of drupal/core-recommended.

Drupal 9 core-recommended's symfony/yaml is constrained to "~v4.4.45"
Drupal 10's is "~v6.3.0"

the 4.x branch (master) of qr-code-bundle: "^5.4||^6.0" constraint on symfony/yaml
the 3.x branch of qr-code-bundle: "^3.4||^4.4||^5.0"

So if we want to keep the qr-code-bundle library, then I think we need to drop d8 and d9 compatibility on our 4.0.x branch
and drop d10 compatibility on our 3.0.x branch

That is of course assuming a core-recommended installation, and I am not 100% sure that core-recommended gets to be the determiner here.

Leaving this as needs review for now

This looks great to me, thanks for addressing it!
