Added a method `Template.toJSON()` to get the object
representation of the CloudFormation template.
This is most useful for snapshot testing.

BREAKING CHANGE: `Template.fromTemplate()` is now
renamed to `Template.fromJSON()` to provide clarity.

Switch all current cfn-only packages to depend on
`assertions` instead of `assert`.

Update `example-construct-library` to showcase using
the `assertions` module.

Update `cfnspec` so that new packages are created with
the `assertions` module.

…plate during tests (#15924)

In v1, the default value of the `@aws-cdk/core:newStyleStackSynthesis` flag is `false`. As a consequence, `Template.fromStack()` generates, by default, a template without the rule and parameter related to bootstrap versions. In v2,  the default value of this flag is `true`. So this test fails in the v2 branch. By explicitly setting the flag to `false`, we ensure that the tests passes on both v1 and v2, regardless of the default values.
