Update Meilisearch version and docker files

[prrao87]

Updates

• Bugfix: Mentioning the minor version of Meilisearch is important, as the docker resolver looks for this when starting the DB
  • Specifying the version as v1.1.1 works as intended
• Improve comments and verify that timing performance results from Improve indexing performance #12 worked as intended
  • The same workflow when working with aiofiles to asynchronously read from files does not perform as well
  • Applying Pydantic validation line-by-line on the JSONL files is slower (expectedly so) than applying Pydantic validation to the entire file's contents as once via a list comprehension.

For now, this seems like the best performance that we can get with Meilisearch!
