`pnpm config get --global` and `pnpm config list --global` printed the
settings from the project's pnpm-workspace.yaml when run inside a
project, and `--global` and `--location=global` disagreed on what the
global config is, although the docs call them the same.
pnpm v12: `ConfigFlags::is_global` resolves both flags in one place,
with `--location` winning. A `get`/`list` scoped that way loads config
the way other global commands do, anchored at the pnpm home, so neither
the project's pnpm-workspace.yaml nor its .npmrc applies. The
pre-command pin checks and the `-w` conflict check use the same helper.
A global config read also implies --ignore-workspace, so
PNPM_CONFIG_WORKSPACE_DIR does not bring a workspace back in.
pnpm v11: config commands turn `--global` into `--location=global`
before loading config, so `--global` no longer loads the config of a
global install. That mode required the global bin directory in PATH and
read the global packages' pnpm-workspace.yaml. The CLI parser lets
`--location` win over `--global` when looking for the workspace.
Both now skip the project .npmrc for these reads, as npm does in global
mode. A new `ignoreProjectNpmrc` getConfig option does it in v11; other
v11 global commands are unchanged.
