Remove dependency on ESLint v8 (EOL)

[MikeMcC399]

What would you like?

• Migrate to using supported version of ESLint (currently v9) (including @cypress/eslint-plugin-dev)

cypress/package.json

Line 147 in b5e2f7a

"eslint": "^8.56.0",

• Migrate to ESLint plugins compatible with ESLint v9

Why is this needed?

Versions of ESLint < v9 are no longer supported since Oct 5, 2024. See https://eslint.org/version-support/.
