Infer type labels from existing labels

Summary

Many of our issues are missing type labels which prevents them from falling through to group triage reports. For some labels we can infer the type label to apply to reduce the number of issues without a known type label

Examples

Original label	Inferred label
~enhancement	~feature
~performance	~bug
security	~bug
~"technical debt"	~backstage *

• If backstage becomes a new type label
