## Description

It seems that there is obsolete configuration code for the `Uploads.html` template in
https://github.com/benjaminkott/bootstrap_package/blob/45333312fceb60fc96a27fd648e8a5547dc230cc/Configuration/TsConfig/Page/TCEFORM.tsconfig#L21

There, two layout options are added and shown in the backend

but never used in the `Uploads.html` template itself as far as I can see.

Instead, the default field `uploads_type` is used for this purpose


We currently use BP12 but the code is also available in BP13 and BP14.

Looking at the history of the `Uploads.html` template it seems that this change happened in BP8 in 2017:
https://github.com/benjaminkott/bootstrap_package/commit/9e9b6c8d0c0405c2ba2957618f8d10a0f1590f1f
Here the template was changed but the configuration was kept.

Maybe the configuration code in TCEFORM is therefore not necessary anymore and can be deleted?

Start with Configuration/TsConfig/Page/TCEFORM.tsconfig at the linked lines, then compare the referenced Uploads.html template and its use of the uploads_type field. Check whether the two layout options are referenced elsewhere in the package; done means obsolete backend options are no longer exposed without affecting the current Uploads.html behavior.
