Avoid evaluation of command substitution in input

In the body of the bash script, `${{ inputs }}` parameters are often quoted with double quotes, which allow command substitution.  This replaces double quotes with single quotes to prevent that and avoid command substitution.

-### Caching even if an intermediate job fails
-
-Just like [the basic actions/cache workflow](https://github.com/actions/cache), this action has a cache restore step, and also a save step which runs after the workflow completes.
-By default, if any job in the workflow fails, the entire workflow will be stopped, and the cache will not be saved.
-
-Due to current limitations in GitHub Actions syntax, there is no built-in option for this action to save the cache even if the job fails.
-However, it does output information which you can feed into `actions/cache` yourself to achieve the same effect.
-For example, this workflow will ensure that the cache is saved if a step fails (but skipping it if the cache was hit, i.e. there's no need to cache it again).
