Have serde serialization match strum.

[csasarak]

Overview

The serialization Serde was producing didn't match what we expected it to. This PR adds renames so that our external serialization is correct as well as tests to keep them updated/in-sync.

I bumped the version to 3 since technically this change is breaking I think - even though in reality I'm not sure it actually would.

Acceptance criteria

• lib-fingerprint outputs the new serialization for fingerprint kinds.

Testing plan

• Test which checks that every value of the Kind enum matches a known good external serialization with no duplicates.
• Test that serde output matches strum.

Risks

If something else depends on the serde deserialization for Kind then that code could break/data could need to be fixed.

Checklist

• I added tests for this PR's change (or explained in the PR description why tests don't make sense).

Yes, this is considered a breaking change since it changes the output data shape 👍🏻
