feat(config): Make ignore comments configurable

[infraredgirl]

Changes:

When a PR is closed, Renovate posts a comment to let users know
that future updates will be ignored. This change makes contents of that
comment configurable via the config file.

Documentation (please check one with an [x])

• I have updated the documentation, or
• No documentation update is required

How I've tested my work (please tick one)

I have verified these changes via:

• Code inspection only, or
• Newly added/modified unit tests, or
• No unit tests but ran on a real repository, or
• Both unit tests + ran on a real repository

I'm wondering if it would be better to use an object for this config, like we do with product links:

renovate/lib/config/options/index.ts

Lines 126 to 141 in e8e99ef

	{
	name: 'productLinks',
	description: 'Links which are embedded within PRs, issues, etc.',
	type: 'object',
	globalOnly: true,
	mergeable: true,
	default: {
	documentation: 'https://docs.renovatebot.com/',
	help: 'https://github.com/renovatebot/renovate/discussions',
	homepage: 'https://github.com/renovatebot/renovate',
	},
	additionalProperties: {
	type: 'string',
	format: 'uri',
	},
	},

It could be called something like userStrings and then have fields like ignoreDigest, ignoreMajor, etc.

Thanks for the review!

Makes total sense. Fixed in a964e86.
