🐛 fix to redirect v6-canary bundles urls to local dev bundles

[thomas-lebeau]

Motivation

Enable local dev bundle to be loaded properly even when the browser_sdk_next_major_version is enabled

Changes

Tweak the redirect rules to account for the v6-canary bundles loaded when the next major feature flags is enabled

Testing

• Local
• Staging
• Unit
• End to end

I have gone over the contributing documentation.

💬 suggestion: ‏I think we should simplify the regex to make it future proof: datatdog-rum(-\w+)?\.js . It's pretty low-risk.

💭 Though I think there is an upside of having the explicit rules: it can serve as docs for the versions we have and always updated.

We have better documentation here though (although a bit outdated): https://datadoghq.atlassian.net/wiki/spaces/RUMP/pages/2523531139/SDK+distribution#CDN

fixed, Mainly for simplification as I'm not totally convinced that it's futureproof, especially with the split bundles initiative, but we will fix it in due time.

I'll update the doc too, thanks
