Feature request: add support for YML file extension for stacks, pkgmanagers

[kbdharun]

All stacks and pkgmanagers should have the YAML file extension to be detected by Apx currently (since it's hardcoded in some places). And when YML is used instead they aren't detected by default (Note: import seems to convert YML file to YAML file).

It would be great if stacks and package managers could detect configs with both YAML and YML file extensions when placed in the local directory (to avoid confusion on the user side).

Sample reference

apx/core/pkgManager.go

Lines 72 to 78 in 36ef027

	func LoadPkgManager(name string) (*PkgManager, error) {
	pkgManager, err := loadPkgManagerFromPath(filepath.Join(apx.Cnf.UserPkgManagersPath, name+".yaml"))
	if err != nil {
	pkgManager, err = loadPkgManagerFromPath(filepath.Join(apx.Cnf.PkgManagersPath, name+".yaml"))
	}
	return pkgManager, err
	}
