fix(ci): read Playwright version without nested shell quoting (#5910)

## Summary

- replace the nested one-line shell quoting used to read the Playwright
package version
- write the resolved version to `GITHUB_OUTPUT` from a multiline shell
step

## Why

The `desktop-v0.5.12` release smoke job failed before executing tests
because Bash received escaped quotes inside command substitution and
parsed the Node expression as shell syntax.

## Validation

- `bash scripts/test-release-ref-contract.sh`
- isolated execution of the new shell fragment with a fixture
`@playwright/test/package.json`, producing `version=1.58.2`
- `git diff --check`
