Order the scripts and follow naming standard in package.json

[trivikr]

Is your feature request related to a problem? Please describe.

The scripts written in base-package.json are not in order and does not follow a naming standard.

Describe the solution you'd like

• Follow the naming standard used by build
  • rename remove-definitions to clean:types
  • rename remove-dist to clean:dist
  • rename remove-documentation to clean:docs
  • rename build-documentation to build:docs
• Arrange the scripts in lexicographical order as follows:

{
	"build": "yarn build:cjs && yarn build:es",
	"build:cjs": "tsc -p tsconfig.json",
	"build:docs": "yarn clean:docs && typedoc ./",
	"build:es": "tsc -p tsconfig.es.json",
	"clean": "yarn clean:types && yarn clean:dist && yarn clean:docs",
	"clean:types": "rimraf ./types",
    "clean:dist": "rimraf ./dist",
	"clean:docs": "rimraf ./docs",
	"downlevel-dts": "downlevel-dts dist/types dist/types/ts3.4",
	"test": "jest --coverage --passWithNoTests"
}

The types are now generated in dist/types, so remove-definitions script can be removed.
