Breaking changes

• ​Change the CSS class prefix to base- (#40205) @michaldudak

The class prefix of Base UI components have been changed from Mui- to base-. This only affects codebases that uses class names verbatim, i.e. not exposed by JS objects such as buttonClasses, but as plain strings or in CSS stylesheets (.MuiButton.root)

To adapt your code to the new pattern:

• replace all occurrences of the regex .Mui([A-Z][A-Za-z]*)- with .base-$1- (so MuiButton-root becomes base-Button-root, etc.),
• replace all occurrences of the regex .Mui-([a-z]*) with .base--$1 (so Mui-disabled becomes base--disabled, etc.).
