Do you know if the first line of the license breaks GitHub License detection?
It would be nice if GitHub can detect it properly (like there https://github.com/golang/go/blob/master/LICENSE)

no need to backport

@julienrbrt good find. Yes, the header is not correct and it breaks the auto detection. I've updated the header.

We can check if the license detector works using:

gh api \
  -H "Accept: application/vnd.github+json" \
  /repos/cosmos/cosmos-sdk/license

Which currently returns:

 ...
  "license": {
    "key": "other",
    "name": "Other",
    "spdx_id": "NOASSERTION",
    "url": null,
    "node_id": "MDc6TGljZW5zZTA="
  }

Note: key should have something like apache-2

after merging this we can check if this fixes the github autodetection.
