Refactor/sempahore abi to utils (#818)

* ci(contracts): a script that moves the abi.json file created to utils folder

A script could be run immediately after compilation to copy the file
artifacts/contracts/Semaphore.sol/Semaphore.json to packages/utils/src/semaphore-abi.json. Then all
packages/apps that need the interface can import it from @semaphore-protocol/utils.

re #817

* refactor(utils): allows packages to import abi from @semaphore-protocol/utils

re #817

* refactor(cli-template-monorepo-ethers): installs ncp and exports Semaphore Abi byte code

re #817

* refactor(contracts): added a script that automates movement of semaphore-abi.json

* chore(cli): changed the dependency and moved to ncp for copying semaphore abi

Changed the importation of abi in utils to _interface and moved the ncp to a dev depency

* chore(utils): changed ab to _interface and update to package.json

* chore(cli): deleted Cli-template file and made a document change

delted some cli-template file, changed yarn commit to git commit and fixed the yarn compile  script

 Semaphore uses [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/). A [command line utility](https://github.com/commitizen/cz-cli) to commit using the correct syntax can be used by running:
 
 ```bash
-yarn commit
+git commit
 ```
 
 It will also automatically check that the modified files comply with ESLint and Prettier rules.
