Error exporting multi-page PDFs when file is read only

[hp6393]

Creating this as a separate issue for tracking purposes:

While experimenting, I also discovered a different error involving multi-page PDFs when the file attribute is set to read only. The error does not occur on single-page PDFs regardless of read only status. However, I get the following error for a multi-page PDF only when the file is set to read only:

{"msg":"Failed to export items.","stack":"Error: EPERM: operation not permitted, copyfile 'C:\temp\test6multipage.pdf' -> 'C:\Users\xxxxxxxx\AppData\Local\Temp\tropy-archive-zazQHN\tropy\test6multipage.pdf'","system":"Windows_NT 10.0.19043 (x64)","time":1647960339657,"version":"1.11.1"}

I can reproduce this on MacOS, with a slightly different error message, but the same behaviour with regards to single- vs multi-page PDFs

{"msg":"Failed to export items.","stack":"Error: EACCES: permission denied, copyfile '/Users/xxx/Downloads/xxx.pdf' -> '/var/folders/3d/4px6x0z50nlcw_v8j14cf3380000gn/T/tropy-archive-DDuvXz/tropy/xxx.pdf'","system":"Darwin 21.5.0 (arm64)","time":1652979631823,"version":"1.11.2-beta.1"}

The latest release should fix this issue. @hp6393 would you be able to confirm whether this solves the issue you have in your project?
