fix: formatting adjustments for docs and Makefile

[mbevc1]

Minor formatting and cosmetic fixes for Makefile help output and docs for create custom-attestation-type. Also clean up trailing spaces. No user facing changes.

Checklist

• Docs are autogenerated from CLI help — make sure the help text reflects your changes
• Helm chart (charts/k8s-reporter/) updated, if needed. Note: these changes live in a separate PR
• Terraform provider and related changes (terraform-provider-kosli, terraform-aws-evidence-reporter, terraform-aws-kosli-reporter) updated, if needed

This is a clean, well-scoped docs/cosmetic PR. No user-facing behaviour changes.

Static analysis ✅

• go build ./cmd/kosli/ — passes
• go vet ./cmd/kosli/ — passes

Findings

• ✅ Previous review nit resolved. The earlier comment about the unwrapped jq-format is now addressed — line 29 reads given in ^jq^-format. A grep across the file confirms every prose reference to jq in the help/example text is now consistently wrapped in ^jq^ (lines 29, 35, 38, 44, 51). The remaining bare jq occurrences are actual CLI flags (--jq) or Go identifiers, which is correct.

• ✅ Trailing-whitespace cleanup. The old text used two-trailing-spaces (Markdown hard line breaks) which rendered inconsistently; removing them and relying on real newlines is a sensible tidy-up. Rendering is unchanged for the help output.

• ✅ Makefile column width (%-15s → %-21s). This is the right value: the longest help target is test_integration_full at exactly 21 characters, so the previous %-15s left longer targets (test_integration, suggest-version-ai, test_integration_full) with misaligned descriptions. The new width aligns all current targets. Minor note: if a longer ##-documented target is added later, this constant would need bumping again — but that's inherent to the fixed-width approach and fine for now.

Testability / tests: Not applicable — pure documentation/help-text and Makefile formatting; no logic changed, so no new tests are warranted.

Summary: Looks good to merge. 👍 Nice attention to consistency (wrapping every jq reference) and to the Makefile alignment math.
