docs(dev): update binaries and release w/ goreleaser changes

- hadn't seen these docs before, so updating them to match all the `goreleaser` changes
  - no need to install various deps, just `goreleaser` with `go mod tidy`
  - no need to install and run `deploy.sh`, just `make snapshot` and `make release`

- update `make snapshot` to remove `--single-target` so that it will build all binaries as a dry-run
  - since it's no longer needed for the default target build, can make it output all binaries

- TODO: modify changelog / release notes / versioning to match Sylvain's current style
  - Didn't change some references to `VERSION` and `deployment.yml` as I will likely make those work with `goreleaser`

- also fix some typos:
  - "developper" -> "developer"
  - "dependancies" -> "dependencies"
  - "gitub" -> "github"
  - "repos" -> "repo"
  - "you" -> "your"
  - "priviledges" -> "privileges"
  - etc

-`deploy.sh` uses `docopts` for parsing our command line option. So you will need to build a first `docopts` and having

-
-build `docopts`:
-
-```
-cd path/to/docopt/docopts
-make
-```
-
-clone and install `deploy.sh` (will be installed by default in `PREFIX=${HOME}/.local`
-
-```
-git clone https://github.com/opensource-expert/deploy.sh deploy_sh
-cd deploy_sh
-make
-make install
-```
-
-if your `${HOME}/.local/bin` is not in your PATH
-
-```
-PATH=$PATH:${HOME}/.local/bin
-```
-
-test
-
-```
-deploy.sh -h
-```
-
 ### deployment steps
 
 In `docopts` project folder.
 
-So you need to create the release text in `deployment.yml` before you run
-`deploy.sh`.
-
-See what will going on (dry-run):
-
-```
-deploy.sh deploy -n

+You need to create the release text in `deployment.yml` first.
 
-Deploy and replace existing binaries for this release.
+Dry-run to create release files and binaries in the `dist/` dir:
 
 ```
-deploy.sh deploy --replace
+make snapshot
 ```
 
-Only build binaries in `build/` dir:
