UpdateServiceWorkerFileWithVersion task runs after static asset compression

[zotanmew]

Describe the bug

The UpdateServiceWorkerFileWithVersion task runs after static asset compression. This causes a content mismatch between the compressed and uncompressed versions of the wwwroot/service-worker.js file.

To Reproduce

• Run dotnet publish in an ASP.NET blazor wasm project with service worker / PWA support enabled
• Compare decompressed contents of service-worker.js.br with service-worker.js
• Decompressed version doesn't contain /* Manifest version: drLIYYR0 */ header (or similar)

Workaround

Place the following in the .csproj or .Build.props:

<PropertyGroup>
    <CompressionExcludePatterns>$(CompressionExcludePatterns);**/service-worker.js</CompressionExcludePatterns>
</PropertyGroup>

I noticed this because the uncompressed content length of the compressed version and the content length of the uncompressed version don't match by a couple bytes (due to the missing header). This may also affect service worker updates.

I'd PR a fix but I'm afraid I'd do more harm than good, the MSBuild task execution flow for static assets is a little bit too complicated for me to understand at first glance
