Maps Ruby's RUBY_PLATFORM to the platform strings used by the Chrome for Testing JSON API and zip file naming conventions.

Definitions

`PLATFORM_MAP`

Ordered list of (pattern, platform) pairs. First match wins.

	[/darwin/, "mac-x64"],
	[/aarch64.*linux|linux.*aarch64/, "linux-arm64"],
	[/linux/, "linux64"],
	[/x64.*mingw|mingw.*x64/, "win64"],
	[/mingw/, "win32"],
].freeze

`def self.current`

Detect the current platform.

Signature

returns　String: e.g. "mac-arm64", "linux64".

end
