`readPackageSync()` could be simplified, 17 fewer deps

[live627]

read-pkg is designated to read package files and optionally normalize them using normalize-package-data. Thing is, only the type attribute is used. https://github.com/avajs/ava/blob/b0b76a034f106dfa34f4ca63da7a3700717857d0/lib/cli.js#L314-L323 Doesn't need to be normalized because it is validated https://github.com/avajs/ava/blob/b0b76a034f106dfa34f4ca63da7a3700717857d0/lib/module-types.js#L1-L25

Could this be simplified?

    let pkg;
    try {
-       pkg = readPackageSync({cwd: projectDir});
+       pkg = parseJson(fs.readFileSync(path.resolve(projectDir, 'package.json'), 'utf8'));
    } catch (error) {
        if (error.code !== 'ENOENT') {
            throw error;

read-pkg could then be dropped

and replaced with parse-json

That in turn could also be dropped in favor of JSON.parse, but then the enhanced error messages would be lost.

I don't think we need enhanced error messages here, if the package.json is corrupted all kinds of other things would also fail. fs and JSON should suffice.

I would like to work on that, if no one is assigned to it :)

[live627]

Neat, now I don't have to 😃

Hi. I've opened a draft PR for this (#2863). I tried my best to do a minimal change to the package-lock.json file, but npm really wants to add dev: true to a bunch of dependencies.

Well, if you have any suggestions, please let me know.

@novemberborn @live627 Hello, the PR is ready for a few days now. Is there anything else I should do to get it approved & merged?

Please let me know. Thanks in advance.

[novemberborn]

@alessandroasm I haven't had a chance to look at it yet.
