Minor development environment setup doc improvements

[hww-nikhilshankarnoble]

Hi CG-Wire team!

I setup a local development environment for Zou for the first time yesterday to test the events system, following the documentation at https://zou.cg-wire.com/development/

While it was very easy to setup, there were a few very small things that caught me out initially that I wanted to suggest as improvements that might make it easier for future users. I'm happy to make these changes myself in a PR but I don't believe the documentation is open-source anymore? I might just be blind, but I couldn't find it under the organisation.

• When installing Meilisearch, it instructs you to pull v1.8.3 but then runs with v1.5 - which causes it to pull again (and the v1.8.3 image is never used). I had some small bumps setting up the indexer (listed below) and this gave me a little confusion over the version I should be using.
• The indexer was originally not working for me when following the setup instructions, I was getting issues that the indexer wasn't initialised. I eventually stumbled across https://zou.cg-wire.com/indexer/#refreshing-indexes which led me to run the DB_PASSWORD=... INDEXER_KEY=... zou reset-search index command that fixed this for me. Not sure if I did something wrong during the setup here but might be worth a mention!
• In order for the tests_search.py module to succeed, the INDEXER_KEY=meilimasterkey environment variable should be set for the py.test command. It would be good to note that this is required - and that ffprobe must be installed for the movie tests to pass.

Thanks!
Nikhil
