Custom search path on a multilingual site

Here is a patch that implements the translatable configuration. Cheers!

@joel_osc this is indeed important, thank you @joel_osc

I'm not sure, if the changes to the controller are really needed and if this is best-practice. Shouldn't a .config_translation.yml do the job for the translatable config values instead?

Would you mind providing a MR and having a look at the best practices?

Happy to review.

I have tried a different approach here. Instead of making the configurations translatable, I have handled it by making changes to search404Goto() method by checking if language module is enabled then append language code to the custom path.

Filename was not correct in https://www.drupal.org/project/search404/issues/3355484#comment-15864755 ✨ Custom search path on a multilingual site Active , hence adding a new patch.

@kuldeepbarot please use a MR instead of patches.

I am not sure that will work for us, since our search urls are different for each language: en/search, fr/recherche. I don't think appending a language is enough.

@anybody - thank-you for your comments, somehow I missed them. I will take another look at the patch and if I come up with something I will add an MR. @kuldeepbarot, happy to discuss your approach and thank-you for helping out on this!
