Update bot to handle new `tool` structure from `changesets` and `@manypkg/get-packages@3`

[marcalexiei]

• Followup to Update @manypkg/get-packages to v3 changesets#1655

Description

The upcoming changesets release introduces Packages type with a different shape for tool property:

https://github.com/changesets/changesets/blob/12f20ea75fb5a440a378bd2bf6072a6bd749fd57/packages/types/src/index.ts#L179-L190

export interface Packages {
  // ...
  tool: {
    type: "yarn" | "pnpm" | "lerna" | "bolt" | "root";
  };
}

This structure aligns with @manypkg/get-packages v3.

The bot currently assumes the previous shape and must be updated to:

• support the new tool structure
• upgrade to compatible versions of both changesets and @manypkg/get-packages

Relevant code:

bot/get-changed-packages.ts

Lines 154 to 161 in a443d06

	let packages: Packages = {
	root: {
	dir: "/",
	packageJson: rootPackageJsonContent,
	},
	tool: tool ? tool.tool : "root",
	packages: [],
	};
