Alexander Hughes aeaf823ecd Bump linter from 1.29 to 1.36
Updating linter to latest version, which also updates
gosec to latest version to keep on top of updated security
checks in source code.

To address security concerns raised by gosec with this update
the MinVersion of TLS is set to 13, as expected in this update to
gosec [0]
