The gitignore file inside `node_modules/` is now an allow list built
from the output of `npm-packlist`. This means that the only dependencies
that get checked in to source control are those that will end up in the
packed tarball, with the exception of some files that we always ignore.

This also moves the dependencies required to build the docs workspace
from devDependencies to dependencies so they are available for making
the docs after pruning. Ignoring these from source control was the
reason that the change to how we build the gitignore file was necessary.

This also removes the release-manager script in favor of the one
provided by template oss.

The cache command itself contains this config making it a circular reference

…cote (#5634)

This also lands the latest `pacote` which now requires passing in an
`Arborist` constructor for use in loading the package tree that gets
passed to `npm-packlist`.

BREAKING CHANGE: `npm pack` now follows a strict order of operations
when applying ignore rules. If a files array is present in the
package.json, then rules in .gitignore and .npmignore files from the
root will be ignored.

BREAKING CHANGE: The default value of `access` is now `public`

Fixes #4994

docs needs to rebuild cmark-gfm which needs to be present in
order to run tests

Also refactor all files written to the logs directory to use the same
code path for file name creation.

BREAKING CHANGE: `--timing` file changes:
- When run with the `--timing` flag, `npm` now writes timing data to a
file alongside the debug log data, respecting the `logs-dir` option and
falling back to `<CACHE>/_logs/` dir, instead of directly inside the
cache directory.
- The timing file data is no longer newline delimited JSON, and instead
each run will create a uniquely named `<ID>-timing.json` file, with the
`<ID>` portion being the same as the debug log.
- Finally, the data inside the file now has three top level keys,
`metadata`, `timers, and `unfinishedTimers` instead of everything being
a top level key.

Closes npm/statusboard#456
