feat: convert from electron-download to @electron/get

[malept]

• I have read the contribution documentation for this project.
• I agree to follow the code of conduct that this project follows, as appropriate.
• The changes are appropriately documented (if applicable).
• The changes have sufficient test coverage (if applicable).
• The testsuite passes successfully on my local machine (if applicable).

Summarize your changes:

BREAKING CHANGE: The download options are completely different.

Depends on:

• feat: add debug support get#94 (debug support)
• Add docs & typedoc support get#93, somewhat (docs support, need to link to a place where all of the options are enumerated)

Blocked by electron/get#96

Basically need to update all the tests to use more recent versions of Electron. Will probably do that in a separate PR.
