Duplicate step name in docs build workflow file

[yousefmoazzam]

Two steps have the same label Generate yaml templates:

httomo-backends/.github/workflows/httomo_backends_docs.yml

Lines 37 to 47 in a34bf58

	- name: Generate yaml templates
	run: |
	pip install httomolib
	pip install httomolibgpu --no-deps
	- name: Generate yaml templates
	run: |
	python ./httomo_backends/scripts/yaml_templates_generator.py -i ./httomo_backends/methods_database/backends/tomopy/tomopy_modules.yaml -o ./docs/build/yaml_templates/tomopy
	python ./httomo_backends/scripts/yaml_unsupported_tomopy_remove.py -t ./docs/build/yaml_templates/tomopy -l ./httomo_backends/methods_database/backends/tomopy/tomopy.yaml
	python ./httomo_backends/scripts/yaml_templates_generator.py -i ./httomo_backends/methods_database/backends/httomolib/httomolib_modules.yaml -o ./docs/build/yaml_templates/httomolib
	python ./httomo_backends/scripts/yaml_templates_generator.py -i ./httomo_backends/methods_database/backends/httomolibgpu/httomolibgpu_modules.yaml -o ./docs/build/yaml_templates/httomolibgpu

The first step shown is incorrectly labelled and should be called something like "Install backends from PyPI".
