* pwsh: handling `z ~` and `z` separately
This patch enables the capability of navigating to the current user's home
directory with `z` when cwd is on a PSDrive that does not have a definition
of the `HOME` location.
Context: The fact that `~` can be counterintuitive on PowerShell, as it's
relative to the cwd, **and its value is defined with a `.Home` property of
cwd's PSProvider\[1]. Not all PSProviders however define this property, leaving
that sometimes you cannot navigate to the undefined `HOME` location with `~`.
To validate this, you can use `Get-PSDrive` to iterate your PSDrives and see
which providers define a `Home` property. On Windows,
```plain
Get-PSDrive C,HKLM | select Name,{$_.Provider.Name},{$_.Provider.Home}
Name $_.Provider.Name $_.Provider.Home
---- ---------------- ----------------
C FileSystem C:\Users\<username>
HKLM Registry
```
or on Linux/macOS,
```plain
Get-PSDrive /,Function | select Name,{$_.Provider.Name},{$_.Provider.Home}
Name $_.Provider.Name $_.Provider.Home
---- ---------------- ----------------
/ FileSystem /Users/<username>
Function Function
```
When cwd is on a PSDrive without a defined `HOME` location, the original
`Set-Location` alias `cd` in PowerShell handles this case by falling back
to the user's home directory when no argument is provided\[2], and when `~`
is explicitly provided, it results in an error.
```plain
PS C:\> Set-Location Function:
PS Function:\> cd ~
Home location for this provider is not set. To set the home location, call "(get-psprovider 'Function').Home = 'path'".
PS Function:\> cd
PS C:\Users\<username>\>
```
This patch implements the same behavior for `z` by handling `z ~` and `z` separately.
