fix(Get-Dependency): correct operator precedence in Parse-Dependency elseif conditions

When DependencyType was set globally via PSDependOptions, PowerShell's
-and/-or precedence caused the simple-string elseif branches to match
even for hashtable-syntax dependencies, assigning the whole hashtable
to Version instead of parsing it correctly.

Parenthesise the (-not $DependencyType -or $DependencyType -eq 'X')
sub-expression in all three branches (PSGalleryModule, GitHub, Git).

Fixes #131
