The solution consists of two parts

MSBuild

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    ...

    <!-- 👇 New extension for ICU files -->
    <NewIcuFileExtension>.icu</NewIcuFileExtension>
  </PropertyGroup>

  ...

  <!-- 👇 After the application is build/published -->
  <Target Name="RenameIcuToAppBundle" AfterTargets="WasmBuildApp;WasmNestedPublishApp">
    <ItemGroup>
      <!-- 👇 Find all ICU files in AppBundle -->
      <IcuFiles Include="$(WasmAppDir)\**\*.dat" />
    </ItemGroup>

    <!-- 👇 Change their extension to 'NewIcuFileExtension' -->
    <Move SourceFiles="@(IcuFiles)"
      OverwriteReadOnlyFiles="true"
      DestinationFiles="%(RelativeDir)%(Filename)$(NewIcuFileExtension)" />
  </Target>
</Project>

Javascript

... = await dotnet
    // 👇 Override resource URL resolution
    .withResourceLoader((type, name, defaultUri, integrity) => {
          // 👇 Override extension of ICU files
          if (type == 'globalization') {
              defaultUri = defaultUri.replace('.dat', '.icu');
          }

          return defaultUri;
      })
    .create();
