Upgrade to ESLint 9

[jattasNI]

Describe the issue

ESLint 8 is end of life on October 5, 2024. @ni/eslint-config-javascript currently depends on "eslint": "^8.57.0",. There is a v9 migration guide that lists several breaking changes. From a quick scan:

1. config files are being renamed from eslintrc to eslint.config.js but there's a way to use the deprecated format
2. eslint:recommended was updated
3. several rule-specific configuration changes

Wondering if we are blocked by the Angular 18 upgrade. Looks like angular-eslint@18.0.0 is the first version to support eslint@v9.

We may also need to contribute to / hasten inlining and migration away from extending the airbnb ruleset as it does not support eslint v9 yet: airbnb/javascript#2961

We may want to do a pass checking our plugins / integrations for eslint 9 support (jsdoc, playwright, and project specific like nimble's prettier-eslint)

Prettier-eslint does not yet support eslint v9, but it sounds like it is coming any day now: prettier/prettier-eslint#1156

Linking some possible predecessor issues to this one:

• Remove dependency on Airbnb ruleset #116
• Stop providing configuration for deprecated formatting rules #148

TypeScript 5.2 support for the using feature of explicit resource management encourages creating block scopes that may have using without any let or const bindings incorrectly triggering rule no-lone-blocks. This is fixed in eslint 9.
