[material-ui][LoadingButton] Make the href prop optional

[Chukwu3meka]

Steps to reproduce

  <LoadingButton
      variant="contained"
      loading={loading}
      sx={{ height: 43, px: 3 }}
      onClick={searchEndpoints}
      startIcon={<SearchIcon />}
      href="">
      Search
    </LoadingButton>

Current behavior

href is required in LoadingButton even though you can pass an empty string to it

Expected behavior

Add a question mark '?' to its interface to make it optional as no every button is a link and since this feature does not mandate href to be a truthy value
