tc.extractZip() failure due to tc.downloadTool() not adding .zip extension

Describe the bug
If no destination is provided when calling tc.downloadTool(), this function defaults to <tempDir>/<uuidv4>. This creates a destination file that doesn't have any file extension, which can apparently cause a subsequent call to tc.extractZip() to fail, with an error like the following:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoLogo -Sta -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -Command "$ErrorActionPreference = 'Stop' ; try { Add-Type -AssemblyName System.IO.Compression.FileSystem } catch { } ; if ((Get-Command -Name Expand-Archive -Module Microsoft.PowerShell.Archive -ErrorAction Ignore)) { Expand-Archive -LiteralPath 'C:\actions-runner\_work\_temp\0f5cb3c0-ca78-43d2-9bf3-19b379b1f416' -DestinationPath 'C:\actions-runner\_work\_temp\882ce538-f7ae-45ef-adc9-32c2ee3cd5e1' -Force } else {[System.IO.Compression.ZipFile]::ExtractToDirectory('C:\actions-runner\_work\_temp\0f5cb3c0-ca78-43d2-9bf3-19b379b1f416', 'C:\actions-runner\_work\_temp\882ce538-f7ae-45ef-adc9-32c2ee3cd5e1', $true) }"
Expand-Archive : is not a supported archive file format. .zip is the only supported archive file format.

Expected behavior
After downloading a proper zip-file with tc.downloadTool(), tc.extractZip() should run without any errors.

Either:

• tc.downloadTool() should default to a destination file that has the same file extension as provided in the given url
• tc.extractZip() should add a .zip extension if necessary
• Both of the above

Start at the tc.downloadTool() and tc.extractZip() entry points and trace how their temporary destinations are chosen and passed to archive extraction. Reproduce the Windows failure with a ZIP URL and verify that downloading and extracting a ZIP without an explicit destination completes successfully.
