feat: add plugin task table to entrypoints form

This commit adds a plugin task table to the entrypoints form. Each task has an "Add to Task Graph"
button which inserts the appropriate YAML to the task graph in a new line. The entrypoint needs to
have plugins that have files with tasks in order for the table to be populated.
