Update in-page sample .env contents and clarify process (#2252)

* Update .env example and clarify process

Update .env contents, and add a little clarification about commands being run. On Windows, for example, you might not have wget, but you'd need to be in the directory with the docker-compose.yml and .env files to run the docker-compose up -d command successfully. (Took me a while to figure out at first)

* Fix some formatting/wording

* Put log level back in and add typesense settings to address PR comments
