Disable out-of-date warnings

[lonix1]

PROBLEM

When mise is installed via package managers (like npm or pnpm), running mise self-update is incorrect because updates must be handled by the package manager instead. The docs actually state that there is a procedure to prevent that altogether.

However, mise routinely prints:

mise WARN  mise version X.X.X available
mise WARN  To update, run mise self-update

That is misleading. It's also unhelpful when we use a delay period to prevent supply-chain attacks - so it's shown every time for 7 days... very annoying.

SOLUTION

Either:

1. The npm package was not created properly (see link above), which I assume would both prevent self update and also silence that warning, or

2. Please give us a setting that silences that specific warning:

   [settings]
   disable_update_warning = true

Thank you!

Confirmed both issues and opened #13028.

The npm packages were missing the update-instructions file that disables self-update. The PR adds it to both the platform packages and the wrapper packages, so npm/pnpm installs direct users back to their package manager.

Disabling self-update alone does not silence the version warning. The PR also adds the requested setting:

[settings]
disable_update_warning = true

Once released, this will suppress update notices in version output and mise doctor, without suppressing other warnings or disabling manual/automatic updates. It also supports MISE_DISABLE_UPDATE_WARNING=true.

For current releases, MISE_SELF_UPDATE_AVAILABLE=false prevents self-update but leaves the version notice. MISE_QUIET=1 mise --version silences it for that invocation, along with other warnings.

Verified the CLI behavior and checked that all seven generated npm package tarballs include the instructions.
