Replace use of deprecated strings.Title

[damccorm]

strings.Title is deprecated as of Go 1.18, and an alternative in to form of golang.org/x/text/cases should be used instead (present in Go since 1.0)

 

An initial exploration found that there isn't a language tag to pass in to cases.Title() that matches the current strings.Title behavior perfectly. More work will need to be done to match existing behavior.
