[Symfony 5.2] Add BinaryFileResponseCreateToNewInstanceRector

[simivar]

Part of #4824

[TomasVotruba]

Better move it to "Symfony" namespace

[simivar]

Don't you think it will be a little crowded there as we want to provide Rectors for 5.0 -> 5.1, 5.1 -> 5.2, and, possibly in the future, more of such migrations? Thanks to a separate namespace it will be as well easy to say which Rector do the changes for which version and what is still lacking in the migration.

[TomasVotruba]

It might. But we should not have 2 standards here, now it looks pretty unclear where to put next Symfony rule.

It might be worth to have major as a split here, rather then 20 directories per minor.

• Symfony2
• Symfony3
• Symfony4
• Symfony5

This PR should handle the split, or add a new rule. Not both.

[simivar]

Should I change the namespace to Symfony5 now and in separate MR split the current Symfony to their respective ones?

[TomasVotruba]

The current namespace is only Symfony. Please use it, then handle renaming/splitting in next PR

Thank you 👍
