Consistent README files for the GitHub home page and repos.

[mark-terminusdb]

Review and implement consistent structure and messaging for:

• Server: https://github.com/terminusdb/terminusdb
• Docs: https://github.com/terminusdb/terminusdb-docs
• Python client: https://github.com/terminusdb/terminusdb-client-python
• JavaScript client: https://github.com/terminusdb/terminusdb-client-js
• Bootstrap: https://github.com/terminusdb/terminusdb-bootstrap

Use consistent language/narrative across readme files and docs pages when describing the same components such as introductions and features.

I added the Python and JavaScript clients above, because they are key parts of our infrastructure. Should others be considered? These are pinned on the organization page:

• terminusdb-store: https://github.com/terminusdb/terminusdb-store/blob/main/README.md
• terminusdb-bootstrap: https://github.com/terminusdb/terminusdb-bootstrap/blob/main/README.md

I made progress. It could be improved upon, but it's not a priority now.
