Feat/create/convert eslint config

[heimwege]

Add a new command create convert eslint-config that converts an existing eslint config of a project that is below eslint version 9 to eslint version 9.
It also adds/upgrades @sap-ux/eslint-plugin-fiori-tools and removes eslint-plugin-fiori-custom.

Additionally

• adds skipInstall option to add eslint-config
• refactors require.resolve to get eslint mjs template in add eslint-config
• fixed create README generator to only show 'required' for required command options (no longer for optional command options with required values).
