Update hash to reference newly uploaded binaries (#64)

Unfortunately, when uploading binaries for the release yesterday, I
accidentally uploaded ones built without our modification.

We want our changes built off of
memfault/memfault-ecs-cli@75eb585,
and I've rebuilt and reuploaded the binaries in
https://github.com/memfault/memfault-ecs-cli/releases/tag/1.21.0 to
reflect that.

## Test Plan
Builds locally with command `conda build -c conda-forge .`
```
<output snipped>
export SRC_DIR=/Users/dansubak/mambaforge/envs/build/conda-bld/ecs-cli_1700684638754/test_tmp
+ ecs-cli --version
ecs-cli version 1.21.0 (*75eb585)
+ exit 0

# Automatic uploading is disabled
# If you want to upload package(s) to anaconda.org later, type:


# To have conda build upload to anaconda.org automatically, use
# conda config --set anaconda_upload yes
anaconda upload \
    /Users/dansubak/mambaforge/envs/build/conda-bld/osx-arm64/ecs-cli-1.21.0.memfault0-0.conda
anaconda_upload is not set.  Not uploading wheels: []

INFO :: The inputs making up the hashes for the built packages are as follows:
{
  "ecs-cli-1.21.0.memfault0": {
    "recipe": {}
  }
}

```

Of note in the above, you can see that `ecs-cli --version` returns the
commit hash we want instead of the old busted one.

## Deploy plan
Will kick off another GH Action run to get these built, then upload the
resulting binaries as per the README. I'll start with the osx one and
test locally to see if `bin/setup.py` picks up the new binary without
additional intervention. Assuming it does, everything should work
without any additional work.
