Use deep link for known limitations

[sjourdan]

Description

#370 updated the link but is tied to v0.7.0
As @eliecharra suggested in a comment, let's use a deep link for always up-to-date documentation!

Like: https://docs.driftctl.com/limitations

Example

Found 9 resource(s)
 - 0% coverage
 - 0 covered by IaC
 - 9 not covered by IaC
 - 0 missing on cloud provider
 - 0/0 changed outside of IaC
You have unmanaged security group rules that could be false positives, find out more at https://docs.driftctl.com/limitations
