Update Goutte to version 4 removing the GuzzlePHP dependency

[rjd22]

The PHPUnit tests seem to not work anymore so I didn't update them but I did an integration test on my own any it seems to work correctly. I'm just making this PR to share my change.

This is a breaking change I would say so you might want me to target it to the 3.0 branch.

Thanks for the PR! If you could target the 3.0 branch that would be great and I can go ahead and review it for merging. I believe it should also be a step forward to resolve #323

@irfan-dahir I rebased it to 3.0.0. I'm also running this on PHP version 8.0 and it's running fine. Do you want me to make a separate PR that enables PHP 8.0 for this package?

[irfan-dahir]

Thanks @rjd22 , I'll test this out and let you know!

As for 8.0, let's put it on hold for a bit. I need to make sure the tests and Lumen framework both support it.

Edit: Glad to know it's working fine on 8.0 tho!

Perhaps add suggests for symfony http client and guzzle.
Documentation also needs to be updated that the correct adapters need to be required.

[rjd22]

@janvernieuwe sadly the Guzzle version is incompatible with the SymfonyHttpClient version. The upgrade is one way. I think dropping guzzle completely for this library on a major version is reasonable.

[rjd22]

@irfan-dahir would it be possible to get this one merged? The old Guzzle version would be really blocking for using the new 3.0 release.

[irfan-dahir]

@rjd22 For sure - I will review and merge it before the end of the week.

Thank you @irfan-dahir !
