add title_bar.inactive_background styles

Hey @tecandrew,
can you give me a hand with this formatting issue I'm having? I just tried adding titlebar inactive color, but for some reason I couldn't get neither zed nor vscode to respect editorconfig. This PR should have been 8 lines instead of entire files with 3k+ total LOC.

@tepavcevic on zed try disabling format on save on the config file "format_on_save": "off" or just add it using vim or nano if it's just one line.
Edit: You can also disable it only for json:

    "JSON": {
      "format_on_save": "off"
    }

[tecandrew]

@tepavcevic we don't modify the generated JSON files directly since we also generate all flavors' accents in each release for those who would like to override the default "mauve" accent

[tecandrew]

keeping the color as catppuccin's "crust" color makes sense. to make the "inactive" state obvious, maybe we can keep some of the "transparent" coloring a bit, but not so transparent since that seems to be the fallback behavior

[tecandrew]

added blur, but I'm not sure it works on Linux yet. it may on MacOS?

slight transparency seems to look OK 😄

edit: seems to do nothing on MacOS. will keep it in there for future possible blur or transparency stuff just in case 🤷

Thanks for the tip @AlvaroParker.
@tecandrew I wasn't familiar with how setting up the theme goes, I'm glad you were eager to jump in and help.
I tested it on ubuntu and it looks really nice 😄
