Incorrect bullet point ordering in docs

[surchs]

This section: https://neurobagel.org/user_guide/maintaining/#updating-the-data-in-your-graph has an incorrect ordering:

Most likely this is because the ordering is restarted by malformatted markdown:

documentation/docs/user_guide/maintaining.md

Lines 92 to 105 in 791e8a1

	1. Shut down the Neurobagel node, if it is already running
	```bash
	docker compose --profile full_stack down
	```
	(or, replace `full_stack` with the profile you are using)
	2. Update the data files in the directory specified by the `LOCAL_GRAPH_DATA` variable in `.env`, or simply change the path to a directory containing your JSONLD files.
	3. (Re)start the Neurobagel node
	```bash
	docker compose --profile full_stack up -d
	```

We should:

• Fix the markdown problem
• Ensure the ordering makes sense
