Let Rails/LinkToBlank also catch cases where link_to_if++ is used

[fwolfst]

Is your feature request related to a problem?

While the cop catches instances where link_to is used, it doesnt catch its sister implementations link_to_if and link_to_unless.

# Bad
link_to_if config.url.present?, config.url, config.url, target: '_blank'

# Good
link_to_if config.url.present?, config.url, config.url, target: '_blank', rel: 'noopener noreferrer'

Describe the solution you'd like

The same cop should catch link_to_ifs and link_to_unlesss matching the conditions

Describe alternatives you've considered

Implementing a separate cop of a configuration value for the given cop.

Additional context

There is also link_to_unless_current which might be more difficult to implement a check against.
