#291 Fix EU REACH, and some other miscellaneous documentation improvements

[Andy-Grigg]

Closes #291

After the move to use the latest version of the Restricted Substances database for CI, we now see the effects of changing from 'REACH' to 'EU REACH':

The REACH legislation 'Short title' was changed from 'REACH - The Candidate List' to 'EU REACH - The Candidate List' to disambiguate from UK REACH, China REACH, Korea REACH, etc. As a result, the examples now return zero results.

This PR replaces 'REACH' with 'EU REACH' everywhere, which should reinstate the results. Check the built docs in the pre-merge checks to confirm.

I have also made a few other miscellaneous documentation changes while I was in the code:

• Fixed a missing space in a connection error string
• Replaced 'localhost' with 'my_server_name', to be consistent with jupyter notebook examples
• Added clarification as to what should be used for the legislation_name parameter. Note that we might change this to use the legislation id instead. At this point we could change the parameter name, causing people to adjust their scripts to avoid a silent failure.
