Support more Tekton task resolvers

[fproulx-boostsecurity]

There are multiplate ways to specify that (https://pipelinesascode.com/docs/guide/resolver/#remote-task-annotations). So basically, we should support when it's /task-\d+

pipelinesascode.tekton.dev/task: "git-clone" # already supported
pipelinesascode.tekton.dev/task: "[git-clone, some-other]" # already supported
pipelinesascode.tekton.dev/task-1: "git-clone"
pipelinesascode.tekton.dev/task-2: "git-clone"
