Fix minor TypeScript issues and add ESLint TypeScript support

Thank you very much for these changes! Just two things to note:

1. There seem to be some indentation issues in tsconfig.json files. I think caused by mixed spaces and tabs for indentation. This should be fixed.
2. Ideally the tsconfig.json files would make use of the standard base configuration for Node 18 (see here). This might cause issues with the required typescript version, which might in turn cause issues with the required eslint version. This could happen outside of this PR.

Thank you for your review.

Firstly, I fixed all tsconfig.json files with 2-spaces indentation. Please check again.

Secondly, the content of all new tsconfig.json was copied from libraries/fabric-ledger/tsconfig.json, which should be the only project written in TypeScript in this repository. Since I want to reduce the chance of causing issues, I assume the existing TypeScript configuration is working and copy it to all the projects with minor modifications. I believe that the configuration should be fine for Node 18. What is your opinion about this? Do you think we should base on the standard base configuration for Node 18?

It's probably better to consider using @tsconfig/node18 separately from this pull request so the current change looks good to me.

Thank you for the contribution!
