Parsing Vault Initialization is still hardcoded at 5 keys instead of dynamic size

First, HUGE thank you for putting this together... I just came across it while working through a tutorial on another site.

At line 1552, you parse the secrets for initializing the vault.

For our org, we wanted to do 7 shares with a threshold of 2.

The script itself does great at actually pushing that, but when it builds the object for the $VaultINITKeys, it makes an assumption that it will have 5 keys.

I did a down-and-dirty cut and paste to expand it for my 7 keys, but a better approach would probably be a foreach loop based on the incoming $initialize variable.

Another possibility, is that the web interface, by default downloads this as a .json file. Possibly just parsing the data a little more "raw" using ConvertFrom-Json would be easier?

I haven't dug in on diagnostics to look at the raw stuff yet, but hopefully this can point this in a direction to make this wonderful toolset a little more generic.
