Property name	Type	Description
runner.name	string	The name of the runner executing the job. This name may not be unique in a workflow run as runners at the repository and organization levels could use the same name.

Additional information

Between https://github.com/check-spelling-sandbox/check-spelling/actions/runs/13813316120 and https://github.com/check-spelling-sandbox/check-spelling/actions/runs/13835035831 the behavior of RUNNER_NAME and the github runner api changed.

In the first run, RUNNER_NAME and runner_name had matching behavior. In the second run, RUNNER_NAME is equivalent to runner_name (with spaces changed to _...) + "_" + runner_id.

Note that there is no id property in the runner context and that the runner context name now appears to include a runner id (at least for github hosted runners).

For my reference, I added code to handle this change:
check-spelling/check-spelling@75e8f6b

which results in things working again:
https://github.com/check-spelling/check-spelling/actions/runs/14014671669/attempts/1#summary-39238824999

Note that nothing mentions that some of these things mangle spaces into -s either...
