Release name shouldn't include invalid characters

[bruno-garcia]

while building Sentry Defenses I notice we append an app name that could contain spaces:

@"release" : @"Sentry Defenses@1.0.1",

We should Regex.Replace any character not valid on the left side of @ with _

Docs state that only invalid characters are:

The release name cannot:

contain newlines, tabulator characters, forward slashes(/) or back slashes()
be (in their entirety) period (.), double period (..), or space ( )
exceed 200 characters

Confirm these (space is OK?) and do the proper validation as specified

The space seems OK. But somehow it changed from io.sentry.game.defenses to Sentry Defenses

You renamed it to Sentry Defenses when you added an icon and the splashscreen: getsentry/sentry-defenses@05b1861#diff-1d4e39902f0b80b0d8badcf7818305afb5b0b31eb8736fba7e17bbaee2da2e8aL16
