fix: not allow install multiple package manager (#161)

When a project has both npm and pnpm, using pnpm/action-setup will result in an error: `Multiple versions of pnpm specified`.

The previous implementation was only meant to avoid the "ERR_PNPM_BAD_PM_VERSION" error, but it did not take into account the situation of multiple different package managers.

 ## Inputs
 
 ### `version`
 
-**Required** Version of PNPM to install.
+Version of pnpm to install.
+
+**Optional** when there is a [`packageManager` field in the `package.json`](https://nodejs.org/api/corepack.html).
+
+otherwise, this field is **required** It supports npm versioning scheme, it could be an exact version (such as `6.24.1`), or a version range (such as `6`, `6.x.x`, `6.24.x`, `^6.24.1`, `*`, etc.), or `latest`.
 
 ### `dest`
 
-**Optional** Where to store PNPM files.
+**Optional** Where to store pnpm files.
 
-### `bin_dest`
+### `run_install`
 
-**Optional** Where to store executables (`pnpm` and `pnpx` commands).
+**Optional** (_default:_ `null`) If specified, run `pnpm install`.
 
-### `registry`
+If `run_install` is either `null` or `false`, pnpm will not install any npm package.
 
-**Optional** Registry to download PNPM from.
+If `run_install` is `true`, pnpm will install dependencies recursively.
+
+If `run_install` is a YAML string representation of either an object or an array, pnpm will execute every install commands.
+
+#### `run_install.recursive`
+
+**Optional** (_type:_ `boolean`, _default:_ `false`) Whether to use `pnpm recursive install`.
+
+#### `run_install.cwd`
+
+**Optional** (_type:_ `string`) Working directory when run `pnpm [recursive] install`.
+
+#### `run_install.args`
+
+**Optional** (_type:_ `string[]`) Additional arguments after `pnpm [recursive] install`, e.g. `[--frozen-lockfile, --strict-peer-dependencies]`.
+
+### `package_json_file`
+
+**Optional** (_type:_ `string`, _default:_ `package.json`) File path to the `package.json`/[`package.yaml`](https://github.com/pnpm/pnpm/pull/1799) to read "packageManager" configuration.
+
+### `standalone`
+
+**Optional** (_type:_ `boolean`, _default:_ `false`) When set to true, [@pnpm/exe](https://www.npmjs.com/package/@pnpm/exe), which is a Node.js bundled package, will be installed, enabling using `pnpm` without Node.js.
+
+This is useful when you want to use a incompatible pair of Node.js and pnpm.

 ## Usage example
 
+### Install only pnpm without `packageManager`
+
+This works when the repo either doesn't have a `package.json` or has a `package.json` but it doesn't specify `packageManager`.

-  steps:

-      with:

 ```
 
+###  Install only pnpm with `packageManager`
+
+Omit `version` input to use the version in the [`packageManager` field in the `package.json`](https://nodejs.org/api/corepack.html).
+
+```yaml

+
+```yaml

+  - pull_request
+

+  install:
+    runs-on: ubuntu-latest
+
+    steps:

+
+### Use cache to reduce installation time
+
+```yaml

+          cache: 'pnpm'
+
+      - name: Install dependencies
+        run: pnpm install
+```
+
+**Note:** You don't need to run `pnpm store prune` at the end; post-action has already taken care of that.
