fix: add configurable timeout setting for OneLogin provider (#137)

This pull request introduces a new configuration option for setting a
timeout in the OneLogin provider. The addition allows users to specify
the timeout for API operations, improving flexibility and control over
API interactions.

### Enhancements to OneLogin provider configuration:

*
[`onelogin/provider.go`](diffhunk://#diff-67f9eb98d74e43b0177e4868b4575c740c8fed94dc98974964d3601c3c609b94R42-R47):
Added a new `timeout` configuration option to the provider schema. This
option allows users to set a timeout in seconds for API operations, with
a default value of 60 seconds. The value can also be sourced from the
`ONELOGIN_CLIENT_TIMEOUT` environment variable.
*
[`onelogin/provider.go`](diffhunk://#diff-67f9eb98d74e43b0177e4868b4575c740c8fed94dc98974964d3601c3c609b94L73-R83):
Updated the `configProvider` function to retrieve the `timeout` value
from the configuration and pass it to the `client.APIClientConfig`. This
replaces the previous hardcoded default timeout.
