Allow CA cert to be passed to the provider as a string

[geekofalltrades]

Terraform Version

Terraform v1.1.4
on linux_amd64
+ provider registry.terraform.io/hashicorp/aws v3.74.1
+ provider registry.terraform.io/hashicorp/kubernetes v2.7.1
+ provider registry.terraform.io/hashicorp/vault v3.5.0

I'm discarding most of the issue template since this is a simple feature request.

Please allow the provider to be configured with Vault's CA cert directly as a string, as described here: hashicorp/terraform#17008 (comment)

This would be incredibly helpful. How on earth has this still not been actioned?

We have the CAs in a string from an output, and we would like to pass that directly to the provider.
