The `ElectronBuilder` strategy uses `YAML#safe_load` to parse YAML
content and this limits deserialization to appropriate classes. We
recently encountered a `Tried to load unspecified class: Time` error
when using the `ElectronBuilder` strategy on a `latest-mac.yml` file
containing `releaseDate: 2022-12-01T02:02:46.419Z`.
The electron-builder YAML files we usually encounter use single
quotes around the `releaseDate` value to ensure it's treated as a
string (e.g., `releaseDate: '2022-10-12T17:55:26.718Z'`) and this is
what we do in `electron_builder_spec.rb`. The aforementioned YAML
file doesn't use single quotes around the value, so it's treated as
a timestamp and apparently this makes Psych use `Time` (which
`#safe_load` doesn't allow by default).
Seeing as we can't control the YAML content and there's a chance we
may encounter other files like this in the future, this commit
modifies the related `#safe_load` call to allow `Time` (and `Date`
for good measure). This will resolve the aforementioned error and
allow the `ElectronBuilder` strategy to work as expected in this
scenario.
