The focus of this commit is to store the dSYM files associated with
official macOS builds. dSYM files allow us to map crash reports to
source.
The dSYM files are primarily uploaded to our official blob storage where
all releases are also stored. We also upload the dSYM files to Sentry
since I'm experimenting with using that for crash reproting (note:
manual crash reporting, no automatic network traffic).
This commit also changes our blob URLs for releases to use the full
Git SHA rather than a build number. This is much easier to trace back.
There are numerous fixes since our previous version (2.5.1) and I
believe at least one is one that users have hit where unarchiving didn't
work properly despite a properly built archive. I'm hoping this improves
that.
Besides this, there is one major security fix. I think it was low risk
to our project currently but I read through it and it is sensible to
protect against the case.
