feat(schema): simplify schema handling

BREAKING CHANGE: schema-path is now hardcoded to ${options.configRoot}/schema.json and can no longer be customized
Before this commit we allowed passing a custom schema path via options.schemaPath that allowed placing the schema in arbitrary locations. While this did provide a little more flexibility, it also required extra code and added complexity. In the name of KISS we are now always defaulting the schema path to ${options.configRoot}/schema.json, which we feel is a sane default and should satisfy the vast majority (if not all) use cases.

your execution environment in the config. For example, assignments like
`key: ${MY_VALUE}` in your config file can be substituted at runtime, resulting
in `key: process.env['MY_VALUE']`. The `substitutionPattern` is an escaped

## Schema Validation
Besides writing config files, you can define a schema file which can be used
Besides writing config files, you can define a `schema.json` file which can be used
to validate your configs. The schema file must be written in JSON according to the
[`json-schema`](https://json-schema.org/) standard. To get started, you can have
a look at the [official learning resources](https://json-schema.org/learn/) or
[`json-schema`](https://json-schema.org/) standard and be placed in the same directory
as your config files. To get started, you can have a look at the
[official learning resources](https://json-schema.org/learn/) or
checkout the examples in the `/example` directory of this project.
You can provide the path to your schema file via `options.schemaPath`. Please
note that this file must be named `schema.json` if you decide to place it in
the same directory as your config files (which is the default).
However, `strong-config` will work fine if you decide to not use schemas at all.
