cb1aed8d - [devtool] inject css as styleTag rather than singletonStyleTag (#81297)

[devtool] inject css as styleTag rather than singletonStyleTag (#81297) Change the style-loader injection for devtool from `singletonStyleTag` to `styleTag` (which is also default). The original setting was configured in #81236 , @mischnic a case where the style is inserted but not applied. Using `styleTag` will insert multi styleTag which can force it layout again when the style is added
