Add refresh token sliding window configuration

[jpoiron]

Version 1.46.0 of FusionAuth introduced the following new configuration options for tenant.jwtConfiguration:

1. refreshTokenExpirationPolicy: SlidingWindowWithMaximumLifetime
2. refreshTokenSlidingWindowConfiguration.maximumTimeToLiveInMinutes

See: https://fusionauth.io/docs/v1/tech/apis/tenants

These changes aim to allow managing these values via the terraform provider. Specifically:

• Added SlidingWindowWithMaximumLifetime as an allowed value for jwt_configuration.refresh_token_expiration_policy
• Added refresh_token_sliding_window_maximum_time_to_live_in_minutes to jwt_configuration for setting a custom TTL value
• Updated documentation

Hi @jpoiron, thanks for the addition. Could you add test coverage for this in resource_fusionauth_tenant_test.go as well?

[jpoiron]

Sure, no problem. Now to figure out how to write tests... :)

[jpoiron]

@mmanes I have updated the tests. Hopefully I did it correctly.

I forgot to try running linting though. Doing that now.

@mmanes Linting errors fixed.
