No provenance template

[arewm]

Expected Behavior

According to SLSA, the buildType should be a type URI for how to interpret the provenance: https://slsa.dev/spec/v1.2/build-provenance#builddefinition

In a SLSA provenance predicate that I have, I see the following buildType

"predicateType": "https://slsa.dev/provenance/v1",
  "predicate": {
    "buildDefinition": {
      "buildType": "https://tekton.dev/chains/v2/slsa",

Unfortunately, https://tekton.dev/chains/v2/slsa reports a "Not Found" error.

Should the buildType be changed to an actual resolvable address or can we put a proper URI specification at that address?

Actual Behavior

The Type URI resolves to how to interpret the provenance
