Function getTruthyBooleanFromEnv

getTruthyBooleanFromEnv(options: GetBooleanFromEnvOptions): boolean
Get a truthy boolean from the environment variables.

Truthy values are: 1, y, yes, t, true, on.
Parameters
- options: GetBooleanFromEnvOptions
  The options for getting the truthy boolean.
  - OptionaldefaultValue?: boolean
    The default value to return if the environment variable is not set.
    
    Default
    undefined
  - OptionalerrorMessage?: string
    Optional error message to throw if the environment variable is not set and no default value is provided.
    
    Default
    "Environment variable <key> is required"
  - key: string
    The key of the environment variable.
Returns boolean
Example
```
import { getTruthyBooleanFromEnv } from '@aws-lambda-powertools/commons/utils/env';

const myEnvVar = getTruthyBooleanFromEnv({
  key: 'MY_ENV_VAR',
  errorMessage: 'MY_ENV_VAR is required for this function',
});
```
By default, the value is trimmed before being converted to a boolean and always required.

You can also provide a default value, which will be returned if the environment variable is not set instead of throwing an error.
Example
```
import { getTruthyBooleanFromEnv } from '@aws-lambda-powertools/commons/utils/env';

const myEnvVar = getTruthyBooleanFromEnv({
  key: 'MY_ENV_VAR',
  defaultValue: true,
});
```
