1156 remove extra release instructions

[jacob720]

Fixes #1156

Instructions to reviewer on how to test:

1. Check the docs on making a release
2. Confirm they link to the mx-bluesky docs on making a release

Checks for reviewer

• Would the PR title make sense to a scientist on a set of release notes
• If a new device has been added does it follow the standards
• If changing the API for a pre-existing device, ensure that any beamlines using this device have updated their Bluesky plans accordingly
• Have the connection tests for the relevant beamline(s) been run via dodal connect ${BEAMLINE}

Sorry, I got the link wrong in the original issue. https://diamondlightsource.github.io/dodal/main/developer/how-to/make-release.html is the correct release instructions.

I think we can just entirely remove this page rather than just delete the contents (and any references to it). I don't think it's useful having a page that is just empty other than the link

[DominicOram]

Sorry, something really weird is happening here. https://diamondlightsource.github.io/dodal/main/developer/how-to/make-release.html doesn't exist in the codebase so there is no duplicate? But if it's not in the codebase why can I still navigate to it? I will investigate.

Some kind of caching maybe? https://stackoverflow.com/questions/17366625/sphinx-uses-old-module-code?__cf_chl_tk=U9ALz09NYPGcK1yxZIO8B1TDAqv5ilR_mgSMugTs03s-1746612515-1.0.1.1-ELdXxypcSYgNbBxwaRpnxRgujfzsxhg5OXZQfTGel1Q

[DominicOram]

I think we probably just want to get rid of the old ones as per https://diamondlightsource.slack.com/archives/CKW8E0V4H/p1744099881688519?thread_ts=1744043386.685669&cid=CKW8E0V4H

[olliesilvester]

Ah yes, let's do that

[DominicOram]

I think this was basically just my mistake, happy to close
