v1.42.3

Fix

• Attribute names containing punctuation beyond -, ., :, @ and * no longer stop a tag from being wrapped over multiple lines. The attribute parser now accepts any character HTML allows in an attribute name, so Alpine key modifiers (@keydown.prevent.?), Angular bindings ((click), [disabled]) and Vue shorthands (#slot) are formatted like every other attribute instead of leaving the whole tag on one long line. Angular bindings also reach --format-attribute-js-json for the first time, which already listed them.
• An unquoted attribute value with a template tag glued to the rest of the value (e.g. src={{ MEDIA_URL }}/logo.png, href={{ .Permalink }}#{{ .Anchor }}) is no longer split into a truncated value plus a bogus standalone attribute when attributes are wrapped; it stays one value, quoted when spread.
