fix: drop patchPnpmEnv so standalone+self-update works on Windows

`patchPnpmEnv` prepended `dest/node_modules/.bin` to PATH before
spawning `pnpm install` / `pnpm store prune`. On Windows in standalone
mode, `.bin/pnpm.cmd` is an npm-created shim that always points at the
BOOTSTRAP pnpm (currently 11.0.4) — the binary npm linked when it
installed `@pnpm/exe` into `node_modules`. The self-updated pnpm
written by `pnpm self-update` lives at `$PNPM_HOME/bin`, which is
separately added to PATH via `addPath()` in install-pnpm.

When the user requested a pnpm version different from the bootstrap
under `standalone: true` on Windows, patchPnpmEnv's `.bin` entry
shadowed the self-updated `$PNPM_HOME/bin` and the action's internal
`pnpm install` ran on the bootstrap. On a pnpm 11.0.x bootstrap this
broke any 11.1+ install flag (e.g. `--no-runtime`), reporting:

    ERROR  Unknown option: 'runtime'

POSIX standalone got lucky because `.bin` and `$PNPM_HOME` resolve to
the same directory there. Non-standalone never tripped on this since
the `.bin/pnpm` symlink for a regular `pnpm` package keeps working
across self-updates.

Removed `patchPnpmEnv` and the now-empty `src/utils/` module.
`spawnSync` now inherits `process.env`, whose PATH is already
correctly fronted by `$PNPM_HOME/bin` and `$PNPM_HOME` via the
`addPath` calls in install-pnpm.

Added `standalone_windows_self_update` to test.yaml as a regression
guard: standalone on Windows + target 11.1.0 + `run_install` with
`--no-runtime`. With the previous code, the install would have run
under the bootstrap (11.0.4) and errored on the unknown flag.

Originally found while building pnpm/setup (the new combined
pnpm + runtime action).
