chore: use community maintained golang-jwt

The dgrijalva/jwt-go project is no longer maintained[1] and they have
transferred ownership to golang-jwt/jwt[2][3][4]. We should move to the
supported golang-jwt/jwt.

The following was performed:

1. update services/httpd/handler*.go to import golang-jwt/jwt
2. revert testcase string comparison changes from 225bcec (back to v3)
2. go mod edit -require github.com/golang-jwt/jwt@v3.2.1+incompatible
3. go mod edit -droprequire github.com/dgrijalva/jwt-go
4. go mod tidy  # see note
5. go clean ./... && go build ./...
6. go test ./...

Note: 'go mod tidy' had unrelated changes (perhaps it wasn't run in
recent commits) so I removed the unrelated delta to keep this PR focused
on the dgrijalva/jwt-go to golang-jwt/jwt changes.
