Update Conda Installation Channel Name in Documentation

[harryswift01]

Summary

Update the Conda installation instructions in the documentation to use the standard lowercase ccpbiosim channel name.

Changes

Update Conda Installation Instructions:

• Change the Conda channel name from CCPBioSim to ccpbiosim in the installation documentation.
• Keep the Conda installation instructions consistent with other CCPBioSim software packages.

Impact

• Documentation-only change.
• No changes to the installation process or package functionality, as Conda channel names are case-insensitive.

Lowercasing the conda install path, this is more convenient for users than having to remember which letters of the org are caps, the default behaviour of most of these tools is to lower case strings internally anyway so this is just aligning the behaviour. We know this works from other repos, happy to merge.
