Monitor all / filter repositories in organization

Is your feature request related to a problem? Please describe.
The dashboard is very handy for monitoring workflow success and failures however the specification of repositories can become quite unruly if an organization has many repositories.

Describe the solution you'd like
Provide the ability to monitor all repositories or allow wildcard matching.

Example: I may have a template repository and client repositories are created from this template with the same naming convention such as:

Test-Repo-Client-A
Test-Repo-Client-B

docker run \
  -p <host machine port>:8080 \
  -e REPO_OWNER_NAME=<organization/username> \
  -e REPO_NAMES="Test-Repo-Client*" \
  -it ottoopensource/gitactionboard:<docker tag>

Example: Monitor all current and future repositories within an organization:

docker run \
 -p <host machine port>:8080 \
 -e REPO_OWNER_NAME=<organization/username> \
 -e REPO_NAMES="*" \
 -it ottoopensource/gitactionboard:<docker tag>

This helps in case there are other contributors creating repositories at random which requires constant updating of the environment variables.

Describe alternatives you've considered
None that I can think of

Additional context
N/A

Start by tracing how the REPO_OWNER_NAME and REPO_NAMES environment variables are read and how repositories are selected for monitoring. Define the behavior for wildcard patterns and for "*", including repositories created later, then verify that the dashboard discovers and monitors the matching repositories.
