Patch the backstage project to support docker build using dind-rootless image

[cmoulliard]

To do

Refactor the bash install script to patch the backstage project in order to support to build the docs using the Mkdocs python tool to:

• Have a new container running dind-rootless
• Configure the techdocs.generator and specifiy the image of mkdocs to be used

docker pull docker:dind-rootless 
docker tag docker:dind-rootless  registry.harbor.10.0.77.176.nip.io:32443/tap/dind-rootless
docker push registry.harbor.10.0.77.176.nip.io:32443/tap/dind-rootless

k patch pkgi tap -n tap-install -p '{"spec":{"paused":true}}' --type=merge
k patch pkgi tap-gui -n tap-install -p '{"spec":{"paused":true}}' --type=merge
