Ignore ci for this commit, should not run on gh-pages

[t92549]

I am not entirely sure why it does fail on this branch though...

[GCHQDeveloper314]

It runs because the CI has been asked to run on all pull requests:

gaffer-docker/.github/workflows/continuous-integration.yaml

Lines 1 to 7 in 828cd34

	name: Continuous Integration
	on:
	pull_request:
	push:
	branches:
	- 'release/**'

It can be changed to something like this instead:

 name: Continuous Integration 
  
 on: 
  pull_request:
    branches:
      - develop
      - v2-alpha
   push: 
     branches: 
       - 'release/**'

[t92549]

I am not sure the ci should fail though, maybe it is okay but seems weird

To be looked at later: #236
