* all: entirely remove minio support

IMPORTANT: Please note this change is NOT active for customers until the
CHANGELOG is updated and clearly states the removal of this for a specific
version of Sourcegraph.

This change entirely removes minio support from our codebase, in favor
of the new Apache-licensed `sourcegraph/blobstore` Docker image:

* All deployment types already no longer use minio, including:
    * Single container `sourcegraph/server`
    * Docker Compose
    * Pure Docker
    * Kubernetes deployment types (helm, kustomize, vanilla, etc.)
    * AMI/image-based 'one click' deployments and script-install deployments
* Removed the Docker image so we no longer _distribute_ any minio code for
  new Sourcegraph versions in the future.
* Removed the ability of Sourcegraph to even configure/use minio in any form.
* Updated third-party license information to reflect the change.

* blobstore: use port 9000 by default (#45105)

All deployments will have blobstore serve on port 9000, so default to
this in the Dockerfile so it doesn't need to be configured everywhere.

* make dev blobstore data/log dirs writable (#45124)

For me, the ~/.sourcegraph-dev/data/blobstore directory was chmod 775, which meant that the blobstore Docker container could not write to it. This caused errors:

- `failed to create bucket: operation error S3: CreateBucket, https response error StatusCode: 403` from the precise-code-intel-worker service
- `sendSimpleErrorResponse: 403 AccessDenied Forbidden` in the blobstore Docker container logs

Making these directories world-writable fixes the problem.

* fix s3proxy (blobstore) port in sg config (#45117)

The blobstore Docker image specifies a container listen port of 9000 (`S3PROXY_ENDPOINT="http://0.0.0.0:9000"`), but this `docker run --publish` flag in sg.config.yaml points to a container port of 80. This commit updates sg.config.yaml to use the correct port (9000).

* blobstore: fix /data file permissions (#45226)

As Quinn noted in an earlier PR, if `/data` is not writable by the container
then we encounter these errors:

- `failed to create bucket: operation error S3: CreateBucket, https response error StatusCode: 403` from the precise-code-intel-worker service
- `sendSimpleErrorResponse: 403 AccessDenied Forbidden` in the blobstore Docker container logs

Docker inherits the permissions of the folder if it is created in the Dockerfile
and I forgot to include the creation of the `/data` folder previously. Fixing
this means we don't e.g. have to manually correct permissions in Docker Compose
or pure-docker deployment types.
