Latest develop fails to build when not using complete AWS bundle SDK

[poikilotherm]

This relates to #5274.

When rebasing on latest develop, my build incorporating a fix for #5274 fails:

[ERROR] COMPILATION ERROR :
[ERROR] src/main/java/edu/harvard/iq/dataverse/DatasetPage.java:[3,46] package com.amazonaws.services.lightsail.model does not exist
[ERROR] src/main/java/edu/harvard/iq/dataverse/ingest/tabulardata/impl/plugins/xlsx/XLSXFileReader.java:[31,46] package com.amazonaws.services.lightsail.model does not exist

This is due to two commits in #5341, which was a resolution for #4680 and #4672, namely 85414f2 in line 31 plus f665bc0 in line 3.

The import is never used and has most likely been introduced accidentally by outcompletion in IDE.

I will provide a fix in a PR later.

@pdurbin could you please drag this to QA? Thx!
(This is a very minor thing and I don't think a code review is needed for this.)

Thx for merging @kcondon! As @pdurbin said: you're on a roll 😉
