sap.m.upload.FilePreviewDialog doesn't show preview for mimetype image/jpg

[geert-janklaps]

OpenUI5 version: 1.24.1

Browser/version (+device/version): Microsoft Edge, Google Chrome, Safari

Any other tested browsers/devices(OK/FAIL): Windows, Iphone

Steps to reproduce the problem:
Currently the file preview dialog doesn't preview a jpg files if the mimetype is set to image/jpg, because the expected mimetype for a jpg file is image/jpeg. (hardcoded in the FilePreviewDialog, see referenced line below)
Some systems set the mimetype for a jpg file to image/jpg (for example SAP Service Cloud).

openui5/src/sap.m/src/sap/m/upload/FilePreviewDialog.js

Line 28 in 9c11476

const PreviewableMediaType = {

What is the expected result?
A preview to be show if the mimetype is image/jpg (same as image/jpeg)

What happens instead?
The file preview not available placeholder is shown
