Subject: [PATCH 1/2] ci: build multi-platform docker images (#2959)

* feat: build multi-platform docker image for Dockerfile.stretch

* chore: temporary always push branch

* ci: update alpine docker build and platform selection

* ci: remove buildx for alpine build, configure pr docker tag

* ci: create multi-platform alpine

* test: temporarily always build multi-arch

* fix: multi-arch alpine build needs docker buildx and qemu

* ci: add new multiplatform workflow; rename or remove old workflows; remove notify jobs

* ci: workflow syntax

* ci: no vars allowed here

* ci: reference current branch for testing

* ci: test docker platforms job

* ci: remove temp workflow settings

-            This PR updates the chainstate file, chainstate consensus hash file, name_zonefile file, and name_zonefile consensus hash file to be used in the creation of the genesis block in the Stacks V2 network:
-            * [chainstate.txt](${{ env.CHAINSTATE_URL }})
-                * Time created: `${{ env.CHAINSTATE_TIME_CREATED }}`
-                * File size: `${{ env.CHAINSTATE_SIZE }} bytes`
-                * MD5 Hash: `${{ env.CHAINSTATE_MD5 }}`
-                    * [Verify the MD5 hash with this script](${{ env.MD5_VERIFY_SCRIPT_URL }})
-                * [Download file](${{ env.CHAINSTATE_DOWNLOAD_LINK }})
-            * [chainstate.txt.sha256](${{ env.CHAINSTATE_HASH_URL }})
-                * Time created: `${{ env.CHAINSTATE_HASH_TIME_CREATED }}`
-                * File size: `${{ env.CHAINSTATE_HASH_SIZE }} bytes`
-                * MD5 Hash: `${{ env.CHAINSTATE_HASH_MD5 }}`
-                    * [Verify the MD5 hash with this script](${{ env.MD5_VERIFY_SCRIPT_URL }})
-                * [Download file](${{ env.CHAINSTATE_HASH_DOWNLOAD_LINK }})
-            * [name_zonefiles.txt](${{ env.NAME_ZONEFILES_URL }})
-                * Time created: `${{ env.NAME_ZONEFILES_TIME_CREATED }}`
-                * File size: `${{ env.NAME_ZONEFILES_SIZE }} bytes`
-                * MD5 Hash: `${{ env.NAME_ZONEFILES_MD5 }}`

-            Once these changes are eventually merged into the `master` branch, a new tag will need to be created. This can be done one of two ways:
-            * Trigger this [Github workflow](https://github.com/blockstack/stacks-blockchain/actions?query=workflow%3Astacks-blockchain) from the `master` branch by selecting "Run Workflow", passing in the desired tag to be created as an argument
-            * Create the new tag from the `master` branch locally and push it up
