Following on from https://github.com/twbs/bootstrap/pull/22500 and its more semantically appropriate use of <input ... readonly>
elements for "static controls", this renames the actual class. Admittedly the new name is a bit long, but very descriptive.
Didn't simply target [readonly]
, because authors may want to retain the input-like look of readonly
inputs, and only apply this new class when necessary/desired.
