ci: add no literals check

[matteo-cristino]

• chore: move from eslint 8 to eslint 9
• ci: add no literals check

[matteo-cristino]

Not totally sure about eslint transition to v9 since I have done it with a tool

npx @eslint/migrate-config .eslintrc.cjs

as stated here https://eslint.org/docs/latest/use/configure/migration-guide#migrate-your-config-file

some literal strings are also set as Javascript expression, thus this test does not find them. By running

ag "{\'[^\']*\'}|{\"[^\"]*\"}"

I found also
