Improve Export Script

[bigdogwillfeed]

We've had tickets on two things recently:

1. script no longer works on powershell 5
2. script is unsigned

For problem 1, this builds on #9 by trying both ways to get the password in plain text. If neither of those work, we fall back to prompting for a plain text string... end result is folks shouldn't be blocked from logging in by their powershell version/environment

For problem 2, this builds on #4 by publishing the signed script as a release (instead of an artifact). Releases are generally easier to find, and are retained longer (artifacts are for only 90 days)

To test:

1. create a manifest
2. run the export script in powershell 5
3. run the export script in powershell 7
4. if you've got an environment where Improve how the $password is converted to plain text #9 was a fix, run the export script there

If that all works and seems nice, we'll tag and generate a release for further testing

This looks good to me. I checked the password handling in powershell 5.1 and 7.5 in Windows and in 7.5 on Ubuntu and the string was parsed properly each time. I wasn't able to reach the API from my Ubuntu session but that seems like a different networking issue because curl couldn't connect either.

Thanks for adding the piece for releasing as well, that seems really helpful 👍
