Update modal to preselect CRC Dataset

https://gitlab.ruhr-uni-bochum.de/FDM/rdm-system/antleaf-projectmanagement/-/issues/74

@anusha Duplicated files from the Hyrax repo

• /app/assets/stylesheets/hyrax/_select_work_type.scss

I then hardcoded some style values (lines 7, 16, 31 and 52) since I couldn't find where the variables $gray, $table-border-color etc were.

• /app/views/shared/_select_work_type_modal.html.erb

Then added checked="checked", to line 13.

<input type="radio", checked="checked", name="payload_concern" value="<%= row_presenter.concern %>"

Please test locally. Currently works by pre-selecting CRC Dataset in the modal.
