Update linting/formatting tooling

[jsumners]

There's a great disturbance in the force. See https://twitter.com/jsumners79/status/1724164412599050587.

We should update our eslint config to use https://eslint.style/guide/migration. Basically, we need to update:

fastify/package.json

Lines 160 to 165 in b4a4138

	"eslint": "^8.51.0",
	"eslint-config-standard": "^17.1.0",
	"eslint-import-resolver-node": "^0.3.9",
	"eslint-plugin-import": "^2.28.1",
	"eslint-plugin-n": "^16.2.0",
	"eslint-plugin-promise": "^6.1.1",

And possibly:

fastify/.eslintrc

Lines 1 to 4 in b4a4138

	{
	"root": true,
	"extends": "standard"
	}

And maybe all of:

fastify/docs/Guides/Contributing.md

Lines 138 to 184 in b4a4138

	Now that VSCode is installed, and we can work with it via the command line, we
	need to install an extension that will aid in keeping any JavaScript you write
	for the project formatted according to the project's style:
	```sh
	code-fastify --install-extension dbaeumer.vscode-eslint
	```
	Upon successful execution of the previous command, the following command should
	result in "found" being output:
	```sh
	[ -d /Applications/VSCodeFastify/code-portable-data/extensions/dbaeumer.vscode-eslint-* ] && echo "found"
	```
	Now, from within the directory of your local clone of the Fastify project, we
	can open VSCode:
	```sh
	code-fastify .
	```
	A new VSCode window should open and you should see the Fastify project files in
	the left sidebar. But wait! We are not quite done yet. There are a few more
	baseline settings that should be set before VSCode is ready.
	Press `cmd+shift+p` to bring up the VSCode command input prompt. Type `open
	settings (json)`. Three [VSCode Setting](https://code.visualstudio.com/docs/getstarted/settings)
	options will appear in the dropdown: Workspace, Default,
	and User settings. We recommend selecting Default. This will open a document
	that is the settings for the editor. Paste the following JSON into this
	document, overwriting any text already present, and save it:
	```json
	{
	"[javascript]": {
	"editor.defaultFormatter": "dbaeumer.vscode-eslint",
	"editor.codeActionsOnSave": {
	"source.fixAll": true
	}
	},
	"workbench.colorCustomizations": {
	"statusBar.background": "#178bb9"
	}
	}
	```

I've opened standard/standard#1948 to discuss with the standard team. Overall, I think we should try to minimize the migration work for us.

Maybe @Fdawgs and others could help.
