Change eslint config to use new flat config format

[dank074]

While attempting to commit I got the following error message:

Oops! Something went wrong! :(
ESLint: 9.13.0

ESLint couldn't find an eslint.config.(js|mjs|cjs) file.

From ESLint v9.0.0, the default configuration file is now eslint.config.js.
If you are using a .eslintrc.* file, please follow the migration guide
to update your configuration file to the new format:

https://eslint.org/docs/latest/use/configure/migration-guide

If you still have problems after following the migration guide, please stop by
https://eslint.org/chat/help to chat with the team.

husky - pre-commit script failed (code 1)

This PR updates the eslint config to use the new flat config format

The CI failed eslint seemingly because the disabled rules are running? Could you have a look at that for me please?

Is this just copy paste'd from #1231 ?

No I ran the migration script myself. Cyber mentioned he had committed these changes but they were not in its own PR

The disabled rules aren't the ones throwing the errors. These are the currently disabled rules:

"no-mixed-spaces-and-tabs": "off",
"@typescript-eslint/no-inferrable-types": "off", // Required by typeorm
"@typescript-eslint/no-var-requires": "off", // Sometimes requred by typeorm to resolve circular deps

and the CI is erroring with the below ones:

  73:39  error  A `require()` style import is forbidden  @typescript-eslint/no-require-imports
Error:    74:18  error  A `require()` style import is forbidden  @typescript-eslint/no-require-imports
Error:   214:24  error  A `require()` style import is forbidden  @typescript-eslint/no-require-imports

/home/runner/work/server/server/src/api/util/utility/EmbedHandlers.ts
Error:   103:11  error  'e' is defined but never used  @typescript-eslint/no-unused-vars
Error:   136:11  error  'e' is defined but never used  @typescript-eslint/no-unused-vars

Going to try to see what's causing it.

Would you prefer that I turn these two rules off, or that I add eslint disable directives to the lines causing problems?

Edit: I added the rules to the disabled list. Let me know if you want me to do the latter instead
