Spacing issue in ColorPicker-Flyout from ColorPickerButton

[Marv51]

Describe the bug

Hi, In moving from Toolkit 7 to 8 I encountered the issue that the size of the Flyout on the first page is too tall. Likely because the second palette page is longer than in the 7.1 design?

I made this screen recording to show the issue: https://github.com/CommunityToolkit/Windows/assets/471338/743fa89b-aaa3-484d-8db6-64e6eb3825a7

Steps to reproduce

Starting from an empty WinUI3 template, I added a ColorPickerButton and the CommunityToolkit.WinUI.Controls.ColorPicker nuget package.

MainWindow.xaml

xmlns:controls="using:CommunityToolkit.WinUI.Controls"
[...]
<controls:ColorPickerButton></controls:ColorPickerButton>

App6.csproj

<TargetFramework>net8.0-windows10.0.22621.0</TargetFramework>
<TargetPlatformMinVersion>10.0.17763.0</TargetPlatformMinVersion>
[...]
<ItemGroup>
  <PackageReference Include="CommunityToolkit.WinUI.Controls.ColorPicker" Version="8.1.240606-rc" />
  <PackageReference Include="Microsoft.Windows.SDK.BuildTools" Version="10.0.26100.1" />
  <PackageReference Include="Microsoft.WindowsAppSDK" Version="1.5.240607001" />
  <Manifest Include="$(ApplicationManifest)" />
</ItemGroup>

Expected behavior

The old design had two pages that where the same height.

I think the spacing of the initial page with the color spectrum can be improved, or the palette page can be condensed a bit so that both pages are of similar height.

Additional context

I did not follow the redesign of this component closely, maybe this was an intentional design change? I can see multiple ways to fix this issue.
