fixes open-telemetry#2608 Ensure that the metric name is greater than the length of the counter suffix ("_total") before checking if it contains the counter suffix to prevent crashes for short (smaller or eq to the length of the suffix) metric names. The edge case where the metric name is "_total" is not handled (considered not to have the suffix), but should not occur IRL. Also fix the spelling of "delimiter".

fixes #2608
Ensure that the metric name is greater than the length of thecounter suffix ("_total") before checking if it contains the counter
suffix to prevent crashes for short (smaller or eq to the length of the
suffix) metric names.
The edge case where the metric name is "_total" is not handled (considerednot to have the suffix), but should not occur IRL.
edit: Use
strings.hasSuffix()to check if metric name has the counter suffix ("_total")Also fix the spelling of "delimiter".
warning: this is one of my first PRs in Go 😅
