Embed feature in UV is pointing to /uv.html instead of /viewer

[escowles]

Bug report from Ben Johnston:

I wonder if I could request a small bug fix in DPUL. I was embedding some IIIF resources in a canvas site and noticed that there seems to be an issue with the IIIF iframe embed code that is made available in the UV viewer in DPUL. It currently points to a file called uv.html which seems to be blank, but it should point to page called 'viewer':

For example, on https://dpul.princeton.edu/cotsen/catalog/37720p047 or any other UV in DPUL, the embed code points to :

https://figgy.princeton.edu/uv.html#?manifest=https://figgy.princeton.edu/concern/scanned_resources/cb91a2fc-541b-4d5d-9f0b-d1e4063f1d41/manifest&c=0&m=0&s=0&cv=0&config=/viewer/config/cb91a2fc-541b-4d5d-9f0b-d1e4063f1d41.json

but I think it should be pointed to:

https://figgy.princeton.edu/viewer#?manifest=https://figgy.princeton.edu/concern/scanned_resources/cb91a2fc-541b-4d5d-9f0b-d1e4063f1d41/manifest&c=0&m=0&s=0&cv=0&config=/viewer/config/cb91a2fc-541b-4d5d-9f0b-d1e4063f1d41.json

it appears to be hard coded into the uv import: https://github.com/pulibrary/figgy/blob/a88508459a7592a9703babf2062aa1be465e6643/public/uv/uv.js#L19379-L19382
and also in https://github.com/pulibrary/figgy/blob/main/public/uv/build.js.map

Can we make /uv.html a redirect to (or just routed be to) /viewer so either URL works?
