validate: Default provider name to base directory when running validate

[austinvalle]

Closes #376

Prior to fix, running from root of terraform-provider-time:

 $ tfplugindocs validate                     
exporting schema from Terraform
compiling provider ""
using Terraform CLI binary from PATH if available, otherwise downloading latest Terraform CLI binary
running terraform init
Error executing command: validation errors found: 
error exporting provider schema from Terraform: unable to run terraform init on provider: exit status 1
Terraform encountered problems during initialisation, including problems
with the configuration, described below.

The Terraform configuration must be valid before initialization so that
Terraform can determine which modules and providers need to be installed.

Error: Invalid provider local name

  on provider.tf line 2:
   2: provider "" {

 is an invalid provider local name: must have at least one character


Error: Invalid provider local name

  on provider.tf line 2:
   2: provider "" {

 is an invalid provider local name: must have at least one character

After fix:

 $ tfplugindocs validate
exporting schema from Terraform
compiling provider "time"
using Terraform CLI binary from PATH if available, otherwise downloading latest Terraform CLI binary
running terraform init
getting provider schema

This fix works (verified locally with terraform-provider-random directory which doesn't work on 0.19.2) and looks good to me 🚀

Not sure if it makes sense to update the --provider-name flag for this default behavior (both in the generate and validate commands). It might also be good to figure out how to integration test this in the future as well.

Added a comment to all the commands (migrate also has it mentioned, so I just adjusted it for them all to follow the same wording) 4729644 ⚡

Re testing: agreed. The txtar archive tests all utilize --provider-name and I think would need to be consistently run in a directory. Perhaps we could add that into the actual archived CLI commands itself eventually? 🤔
