Quoted keys and values are not parsed correctly

[rcjsuen]

It's okay to put quotes around the individual keys and values of a key-value pair in ARG, ENV, and LABEL. They should of course be stripped out from the actual value.

FROM alpine
ARG "aaa"="bbb"
ENV "ccc"="ddd"
LABEL "eee"="fff"
RUN echo $aaa
RUN echo $ccc

$ docker inspect a351391c8188 --format={{.ContainerConfig.Labels}}
map[eee:fff]

However, the quotes seem to be confusing the parser and it's causing the value to not be calculated correctly. The name is also not being stripped of the quotes.

import { DockerfileParser, Label } 'dockerfile-ast';
import { TextDocument } from 'vscode-languageserver-types/lib/umd/main';

const content =
`ARG "aaa"="bbb"
ENV "ccc"="ddd"
LABEL "eee"="fff"`;

let dockerfile = DockerfileParser.parse(content);
console.log(dockerfile.getARGs()[0].getProperties()[0].getName());
console.log(dockerfile.getARGs()[0].getProperties()[0].getValue());
console.log(dockerfile.getARGs()[0].getProperties()[0].getUnescapedValue());
console.log(dockerfile.getENVs()[0].getProperties()[0].getName());
console.log(dockerfile.getENVs()[0].getProperties()[0].getValue());
console.log(dockerfile.getENVs()[0].getProperties()[0].getUnescapedValue());
console.log((dockerfile.getInstructions()[2] as Label).getProperties()[0].getName());
console.log((dockerfile.getInstructions()[2] as Label).getProperties()[0].getValue());
console.log((dockerfile.getInstructions()[2] as Label).getProperties()[0].getUnescapedValue());

"aaa"
="bbb"
="bbb"
"ccc"
="ddd"
="ddd"
"eee"
="fff"
="fff"
