fix: add doctrine common to dependency list in composer.json

[Ahummeling]

As described in #1745 , the PR hopes to resolve a missing dependency on doctrine/common that is encountered when upgrading doctrine/orm to 3.0.x.

Running composer update --prefer-lowest installed the 2.0.x version of doctrine/orm.
Running composer why doctrine/common informed me that doctrine/orm 2.14.0 requires doctrine/common (^3.0.3)

Running composer req doctrine/common ^3.0.3 added the dependency as resulted in the change for this PR

After implementing this change, and installing this branch into my project, the issue was resolved.

I think the right way to address this would be to use the DefaultProxyClassNameResolver introduced in doctrine/orm#11009

I agree that this is probably a better solution.
But doctrine/orm is currently a dev dependency (require-dev) of the bundle package. Please correct me if I'm wrong, but any application installing doctrine/doctrine-bundle without doctrine/orm, won't install doctrine/orm and the same error would occur. Right?

So in addition to using the DefaultProxyClassNameResolver, we'd also have to move doctrine/orm from require-dev to require and set the version to: ^2.17|^3.0, right?

I created a new PR (considering the change is entirely different) #1747. If you agree that that approach is more suited, please feel free to close this PR and we can work on getting the new one merged, thanks.

Sorry, the same error as what?

The "class not found" error, but as discussed in the other PR, that will not be the case, because we have already confirmed doctrine/orm is installed at this point.
