[docs] docs: fix British spellings in frontmatter-full.md

[github-actions]

Summary

The daily spellcheck flagged 1,885 potential findings across 208 docs files. Nearly all of them are false positives from cspell's dictionary — product/tool names (toolsets, agentics, GHES, zizmor, poutine, etc.), usernames (pelikhan, dsyme, mnkiefer), code identifiers, and intentional typo examples used to illustrate the CLI's fuzzy-matching / "did you mean" features (e.g. audti-workflows, permisions, mondey).

After manually triaging the findings, the only genuine spelling issues were British-English spellings inconsistent with the project's American English convention, all confined to docs/src/content/docs/reference/frontmatter-full.md:

• behaviour → behavior (2 occurrences)
• customise → customize (2 occurrences)
• parameterise → parameterize (4 occurrences)

View Details

Note: frontmatter-full.md is auto-generated from the JSON Schema comments (pkg/parser/schemas/main_workflow_schema.json). This PR only updates the generated doc per the spellcheck workflow's scope (docs/src/content/); the schema source itself is outside that scope and wasn't touched, so a future regeneration could reintroduce these spellings unless the schema comments are also corrected separately.

Test plan

• Verified each changed word against surrounding context to confirm it wasn't a proper noun, code symbol, or intentional example
• Confirmed all other high-frequency flagged words correspond to real technical terms, product names, or deliberate typo demonstrations (not spelling errors)
• git diff reviewed — only the 8 targeted word substitutions changed, no other content touched

Refreshed from main, updated the schema source alongside the generated reference, and ran pr-finisher. make fmt, make lint, make test-unit, make recompile, and the final pre-push gate pass. make test has one unrelated Copilot installation-step test failure reproduced on origin/main. No review threads remain; CI has no failed jobs but must be re-triggered by a maintainer, and the PR remains blocked pending required checks/approval.
