Fixes #60397.

error TS5096 currently says

Option 'allowImportingTsExtensions' can only be used when either 'noEmit' or 'emitDeclarationOnly' is set.

But in fact rewriteRelativeImportExtensions also works (as you can see from the line above the change in src/compiler/program.ts in this PR), and is often what I at least am reaching for. This PR updates it to read

Option 'allowImportingTsExtensions' can only be used when one of 'noEmit', 'emitDeclarationOnly', or 'rewriteRelativeImportExtensions' is set.
