Stryker Error: 'svelte/compiler' no longer exports a walk utility in svelte version 5+

[jacq42]

The svelte-parser.ts imports the (deprecated) walk function from svelte compiler:

const { parse: svelteParse, walk, preprocess, VERSION } = await import('svelte/compiler');

When running stryker tests after updating, I got the error message:

 ERROR Stryker Unexpected error occurred while running Stryker Error: 'svelte/compiler' no longer exports a `walk` utility — please import it directly from 'estree-walker' instead
