fix: specify custom attestation type

[mbevc1]

Previous PR #891 didn't provide custom attestation type (https://github.com/kosli-dev/cli/pull/891/changes#diff-ec60bba356baa9a1db241eb6796050a8c987897efa9784975f6a9174085eb1d9R17) in the Flow template. This is fixing this 🚀

Static Analysis

All checks pass — go build, go vet, and go mod tidy report no issues. (This is a YAML-only change, so expected.)

Review

The fix is correct. The custom attestation type requires the custom:<name> format — bare custom is not a valid type. This is confirmed by the attestation reporting code in cmd/kosli/attestCustom.go:194 and the test cases in attestCustom_test.go, which all use the custom:<name> pattern (e.g., custom:person).

The change from type: custom → type: custom:four-eyes-result on line 17 of main-flow-template.yml correctly matches the attestation name on line 16.

No issues found. This is a minimal, targeted fix for a real bug introduced in #891.
