Ion-input accepts any string value

Editor assessment

Well-formed fix with an accurate input scope and a footer token 'Resolves #19884' linking the issue; capitalization of the token does not affect validity. The subject 'ion-input accepts any string value' repeats the component name in both scope and subject, which is mildly redundant, and the phrasing is declarative rather than imperative. More substantively, removing the value restriction sounds potentially behavior-changing; if any consumers relied on validation, a breaking-change argument could be made. As written, patch-level inference is reasonable. The body is minimal but sufficient for the size.
