[pickers] Fix usage with Typescript 4.8

[flaviendelangle]

Fixes #6134

• Use @ts-expect-error to be aware if the error goes away in the future
• Change the file extension to .d.ts to avoid having the @ts-expect-error comment removed during the build

Could some of you test this fix on your applications ?
You just have to put the following line in place of the @mui/x-date-pickers in your package.json:

{
  "@mui/x-date-pickers": "https://pkg.csb.dev/mui/mui-x/commit/111f26e8/@mui/x-date-pickers",
  "@mui/x-date-pickers-pro": "https://pkg.csb.dev/mui/mui-x/commit/111f26e8/@mui/x-date-pickers-pro", // Only if you need it
  "@mui/x-license-pro": "https://pkg.csb.dev/mui/mui-x/commit/111f26e8/@mui/x-license-pro", // Only if you need it
}

I tested it on the reproduction case of @Methuselah96 and it seems to work.

@flaviendelangle Build is green!

I will release it in tomorrow's patch
I let it open until then in case some other want to test and to give feedbacks 👍
