Clarify that the restore-keys input is a string in the docs (#1434)

* Fix Description for restore-keys at Readme

As previously the restore-keys were defined as an ordered lists which is
wrong as per the issue description where the actual format is a
multi-line string with one key per line.

* Added a space between the sentence of restore-keys description

While at the PR review it's been identified there's a need for a space
between the sentence

	```
	An ordered multiline string listing the prefix-matched keys,that are
	used for restoring stale cache if no cache hit occurred for key.
	```

where it's written as "prefix-matched keys,that are" this commit will
address the review comment and introduce a space between
"prefix-matched keys, that are" and change the sentence to

	```
	An ordered multiline string listing the prefix-matched keys, that are
        used for restoring stale cache if no cache hit occurred for key.
	```

* Change restore-keys description at cache/restore/action.yml and cache/action.yml
