fix: Prefer no duplicate imports and no type imports

[ChaituVR]

Context snapshot-labs/sx-monorepo#521 (comment)

Summary:

• import/no-duplicates to not allow duplicate imports:

  import { CHAIN_IDS } from '@/helpers/constants';
  import { SUPPORTED_VOTING_TYPES } from '@/helpers/constants';

  will resolve to

    import { CHAIN_IDS, SUPPORTED_VOTING_TYPES } from '@/helpers/constants';

• @typescript-eslint/consistent-type-imports' to not allow import type

  import type { OffchainNetworkConfig } from './types';

  will resolve to

   import { OffchainNetworkConfig } from './types';

How to test:

• Go to any project, for example, in mono repo, edit package.json,
• Under eslintConfig add config from this PR (add double quotes)
• Try to add duplicate imports and imports with type keyword

TODO:

• Run yarn release to update versions, before merging this PR
