`Tools.Tests.ps1` checks the version of `brew` with `--version` argument.
```powershell
Describe "Homebrew" {
It "homebrew" {
"/home/linuxbrew/.linuxbrew/bin/brew --version" | Should -ReturnZeroExitCode
}
}
```
`SoftwareReport.Common.psm1` checks it with `-v` argument.
```powershell
function Get-HomebrewVersion {
$result = Get-CommandResult "/home/linuxbrew/.linuxbrew/bin/brew -v"
$result.Output -match "Homebrew (?<version>\d+\.\d+\.\d+)" | Out-Null
return $Matches.version
}
```
Generally, `--version` and `-v` are equivalent. But a recent bug in `brew` makes `-v` returns the output of `brew help`.

It's best to maintain consistency in version checks and explicitly use `--version` in both places.
