middleware/parameter.go: fix comment describing ParseForm fallback

[Copilot]

The comment describing the form-parsing helper's Content-Type routing was misleading: it said "otherwise → ParseForm", implying only application/x-www-form-urlencoded triggers ParseForm. In reality, all non-multipart content types fall through to ParseForm — matching the actual logic in form.go.

• middleware/parameter.go: replace otherwise → ParseForm with an explicit statement that all non-multipart types, including application/x-www-form-urlencoded, route to ParseForm

According to form.go lines 243-248, only multipart/form-data triggers ParseMultipartForm; all other content types (including application/x-www-form-urlencoded) go through ParseForm.
