chore!: Normalize repository, dropping node <10.13 support

[sttk]

This PR updates this repository for the following points:

1. Upgrades dependencies and drops node <10.13 support

   • yargs's version is 16, not latest, because the latest version 17 supports node >=12.
   • marked-man version is 0.7, because the latest version 1.3 is esm.
   • eslint, expect, and mocha upgrades to the last versions which supports node v10.
   • Other dependencies upgrades latest versions.

2. Stops using gulp-test-tools

   Because gulp-test-tools was used for nodejs v0.10.

3. Replaces ansi-color and color-suuport to chalk

   Because this package used chalk originally, and chalk enables to drop the codes for --color/--no-color flags.

4. Drops isobject and array-sort

   By adding alternative codes.

5. Drops old gulp supports

   This PR removes ^3.7.0, ^4.0.0-alpha.1, and ^4.0.0-alpha.2 directories.

6. Change directory configuration.

I'll make a PR for using theming-log after this PR.

@sttk why did you remove support for gulp 3.x? This package is supposed to support all versions of gulp we can.

[sttk]

@phated Since gulp-cli is added dependencies of gulp, gulp-cli is not needed to install globally and we can think that new gulp-cli is used in new gulp.
In addition, it's difficult that we'll continue to support gulp v3 on new node and new versions of dependencies.
So I think it's better to remove supporting gulp v3.

@phated I've modified Liftoff.configFiles as I wrote in liftoff#126.

Since gulp-cli is added dependencies of gulp, gulp-cli is not needed to install globally and we can think that new gulp-cli is used in new gulp.

The purpose of this is to allow the node_modules/.bin/gulp to be placed when having the gulp dependency, but we don't want users to be installing gulp globally. Instead the gulp-cli project should be installed globally and needs to support each version of gulp.

In addition, it's difficult that we'll continue to support gulp v3 on new node and new versions of dependencies.

We can update dependencies and node versions while still supporting gulp 3 and gulp 4. The versioned directory allows for us to have isolated code for each one. Please restore the gulp 3 support in this PR.

Additionally, I was trying to review this PR but it seems like you renamed and moved files around without much purpose. Can you reduce this PR to the dependency upgrades/changes and normalization for an easier review? We can add follow up PRs that refactor.

Note to self: Include this rename in the conventional commits so it shows in changelog

@phated I've reverted the two commits about dropping old gulp supports and changing directory configuration. Please review this PR again.

[phated]

Thanks @sttk! This is excellent work. I had a few questions and comments that I'd like addressed.

[sttk]

@phated I've done except the matter regarding archy, pretty-hrtime, and merging config by mergeConfigToCliFlags, mergeConfigToEnvFlags. It will take a little more time for these remaining matter, so please wait for a while.
