Allow variables for keys

[johansmitsnl]

I have a backend that returns errors with a translation key. These errors are not translated because the UI sometimes needs to make changes to certain explanations that the backend is unaware of.

I face 2 issues:

1. Adding the translations makes the check_translations panic because keys are not used in the code
2. When trying to use the translation key as the input the macro panics.

Example of point 2:

let backend_key = "error-backend";

move_tr!(backend_key);

How can I solve this?

You can put these translations in a file that is not added to check_translations glob.

2. When trying to use the translation key as the input the macro panics.

This is not currently implemented in leptos-fluent. The idea is to follow the definitions of variables passed to tr! macros after parsing definitions with literals, to make check_translations work with them. It should be a bit tricky because variables can be used from other files. PRs welcome.

The 1st is indeed a smart option.

I'll check if I'm able to create a pr.
