Migrate to pnpm (#2828)

* chore: 🤖 remove packageManager field from package.json

* chore: 🤖 migrate yarn resolutions to pnpm overrides

* chore: 🤖 generate pnpm-lock.yml by using: pnpm import yarn.lock

* chore: 🤖 remove yarn.lock file

* chore: 🤖 migrate workspace configuration

* chore: 🤖 remove .yarn and .yarnrc.yml config

* chore: 🤖 update .copyright.hcl to ignore root pnpm files

* chore: 🤖 migrate husky pre-commit hook from yarn to pnpm

* chore: 🤖 migrate package.json scripts from yarn to pnpm

* chore: 🤖 update rose package.json & build to use explicit deps

* chore: 🤖 remove unused cp metadata.json command in pjson script

The cp metadata.json to dist was added in:
d19a251

The addons/rose/metadata.json no longer exists so it can't be copied

* chore: 🤖 migrate electron-app package.json scripts to pnpm

* chore: 🤖 create pnpm workspace for electron-app w/ hoisted deps

* chore: 🤖 migrate electron-app yarn lockfile to pnpm lockfile

Used "pnpm import yarn.lock"

* chore: 🤖 migrate electron-app overrides

node-gyp isn't needed since the fork is used via @electron/node-gyp
see: https://github.com/electron/node-gyp?tab=readme-ov-file#node-gyp---nodejs-native-addon-build-tool

* chore: 🤖 add trusted deps to be built to onlyBuiltDependencies

This is a pnpm feature that increases security. By defining these
dependencies they are being trusted to allow install hooks,
including postinstall. See:
https://pnpm.io/settings#onlybuiltdependencies

* chore: 🤖 add electron-app pnpm files to copyright header ignore

* chore: 🤖 remove yarn references from .*ignore files

* chore: 🤖 migrate --yarn to --pnpm for ember-cli-update.json

This isn't clearly documented but something that is supported
and can be found in other ember apps:
https://github.com/search?q=--pnpm+ember-cli-update.json&type=code

* chore: 🤖 migrate ci and related scripts to use pnpm

The cache is migrated to use the cache supported by
actions/setup-node@v4, an action we are already using. This is the
recommended way by pnpm:
https://pnpm.io/continuous-integration#github-actions

This commit also ensures that all github actions are using
consistent versions of actions/setup-node and pnpm/action-setup

* docs: ✏️ update documentation to use pnpm instead of yarn

* chore: 🤖 use explicit asciinema-player dependency

Because we override styles on asciinema-player we depend on their
styles. What might be a minor non-breaking change in their version could
(and did) break our style expectations in our overrides.

* chore: 🤖 run pnpm install and commit lockfile changes

* chore: 🤖 Remove ember-inflector from being overidden

https://github.com/hashicorp/boundary-ui/pull/2828#discussion_r2109847938

* chore: 🤖 remove additional unnecessary files from ignore files

* docs: ✏️ fix pnpm doc links

* chore: 🤖 use corepack to specify packageManager in package.json

* chore: 🤖 let pnpm action in ci use packageManager for version

https://github.com/pnpm/action-setup?tab=readme-ov-file#version

* docs: ✏️ fix broken pnpm website links
