TMJ files are cached for 24 hours during development, changes not picked up

[jannikbest]

Description

When running the dev server, changes to .tmj map files are not picked up by the browser. The map remains stale until the browser cache is manually cleared.

I think, this is caused by the Express static middleware in @workadventure/map-starter-kit-core serving all static files (including .tmj) with maxAge: "1d":

const staticOptions = {
  maxAge: "1d",
  etag: true,
  lastModified: true
};
const staticMiddleware = express.static(".", staticOptions);

The browser caches the TMJ file for 24 hours and never re-requests it from the server, making iterative map development impossible.

Expected behavior

During development, changes to .tmj files should be reflected immediately after a browser reload.

Last working version

I have a repo based on commit c43d94d of the map-starter-kit where this issue does not occur.
