Fix deprecated $defaultName

[ruudk]

This fixes a deprecation on Symfony 6.1:
The "Symfony\Component\Console\Command\Command::$defaultName" property is considered final. You should not override it in "Ekino\NewRelicBundle\Command\NotifyDeploymentCommand".

We cannot use #[AsCommand] as that will still complain about the $defaultName being overwritten... and we have to support SF 3.4.

@jderusse Can this be merged please?

CI needs to be fixed first to assert your PR pass the testsuite. Would you mind to open a PR to downgrade composer in PHP 7.1

[ruudk]

Not going to do that. PHP 7.1 is EOL for years.

I would be able to create a PR to drop all EOL PHP versions.

[CRC-Mismatch]

Easiest bet is my PR #281, it has fixed CI and all, but it's either restricting support for newer Monolog versions or dropping 7.1 🤷‍♂️
I mean, even composer itself needs a whole workaround to work in CI with 7.1, as of now...

Decided that the best thing to do is to remove this bundle + dependency completely from our project.

It was added in the project years ago, a time where "there is an app a bundle for that™️" was the way to go. But we've learned our lesson, dependencies should not be added that easily.
