Suggestion: Add a doc page on known issues

[ray6080]

There are some known issues in the system that won't be address in the near future.

An example is https://github.com/kuzudb/kuzu/issues/3002, which is due to bugs in third party lib. We'd better document it in our docs before we can resolve it.

Keeping a list here for suggestions:

• [x] https://github.com/kuzudb/kuzu/issues/3002. (no longer an issue)
• [x] Explorer not able to auto reflect newly changes from other processes.
• [x] Not able to limit concurrent read/write connections within the same process https://github.com/kuzudb/kuzu/issues/3295
