Fix invalid dependency version bounds (#99)

## Summary

- replace wildcard `MaximumVersion` values with the valid `1.999.999`
upper bound for `Admin` and `Fonts`
- allow PSResourceGet to package and publish the next NerdFonts release

## Validation

- `Invoke-Pester -Path .\tests\NerdFonts.Tests.ps1`
- verified the generated NuGet dependencies are `[1.1.0, 1.999.999]`
