artist/album/track replace mappings

[Cameo007]

Is your feature request related to a problem? Please describe.
There are some cases where alexa doesn't transcribe words the right way like when I say "U2" it understands "U two".

Describe the solution you'd like
I'd like to have a mapping of replacements so AskNavidrome would replace "U two" with "U2".
I don't think that env variables are a good way to do this if you have lots of mappings a config file (e.g. JSON) could be a good solution.

{
    "artists": [
        { "U two": "U2" }
    ],
    "albums": [
        { "some album name": "abc" }
    ]
    "tracks": [
        { "some part of a track name": "abc" }
    ]
}

What I described in this example too is the possibility to seperate the mappings per "use-case" so you had different mappings for artists, album names and track names.

Describe alternatives you've considered
I tried to switch the language of my echo to english (I translated the alexa.json to german via AI for now) but that didn't help.
