chore: update scripts/port_status for more flexible tagging (#17056)
In https://github.com/leanprover-community/mathlib/wiki/mathlib4-port-status we would like to be able to write more complicated statuses, like
* `Yes mathlib4#999 1234abcd` to track commit information about the port
* `No blocked by ring tactic`
* `No PR'd as ...`
This update to the script checks if the status starts with `Yes` or `No` to determine status.
Further, when reporting good candidates for porting, it includes the comment after `No` if present.
