Code formatting: Splatting input parameters before `Invoke-FabricRestMethod` calls

[NowinskiK]

There is an idea to format input parameters as splatting with hash tables.
All original code files from @tiagobalabuch use multiple lines with ` characters.
Example:

        $response = Invoke-FabricRestMethod `
            -Uri $apiEndpointUrl `
            -Method Post `
            -Body $bodyJson

New format suggested by @jpomfret :

            $apiParams = @{
                Uri    = $apiEndpointURI
                method = 'Post'
                body   = $bodyJson
            }
            $response = Invoke-FabricRestMethod @apiParams

These are cosmetic changes and should not impact the current code logic.
