Release 0.4.1: bumps package.json to 0.4.1. The CHANGELOG section is already on publish.

What ships (already on publish):

• env reaches the intake as the ddtags query parameter (🐛 send env to the intake as the ddtags query parameter #33)
• the stored remote configuration survives an application upgrade (fix(rum): keep remote settings across app upgrades #32)

After merge: tag the merge commit v0.4.1, run Publish with dry_run: true, then publish.
