Adding PrepareForBuildDependsOn section as instructed disables PreComputeCompileTypeScriptWithTSConfig task

### Description

The documentation suggests adding a `...` section to integrate TypeScript compilation into the project, however doing so will cause the `PreComputeCompileTypeScriptWithTSConfig` task to be skipped, possibly because the `tsconfig.json` file is not yet available in the content file list at that stage in the build? The end result is that `tsconfig.json` cannot be used when the `PrepareForBuildDependsOn` element is added as instructed in the documentation.

This is potentially additionally a more critical issue in the .net 9 SDK, as it appears the build will error at the static file fingerprinting stage if the `PrepareForBuildDependsOn` element is NOT added.
