v10: Run TF directly via workflow input in addition to PR comments

[rdhar]

Highlight

In addition to the existing PR comment trigger, support TF execution directly via command_input within the workflow to enable more flexible and dynamic use-cases, including parallel runs in matrix strategy.

Added

• Support TF execution directly via command_input string.
• Multiple workflow examples with associated permissions and triggers for usage clarity.
• Cache TF plugins to speed up workflow run times, optionally.
• TF Tests workflow to validate GitHub Action against various sample Terraform configurations.
• Badges/shields at the top of the README to show(-off) notable metrics and metadata.
• Support recreate_comment boolean flag to optionally delete and re-add PR comments after any updates/commits made on the PR branch to make the conversation easier to follow.
• Support -concise flag to reduce verbosity of OpenTofu output.

Changed

• Streamline calls to "github-script" with await require(...) one-liner.
• Rename GitHub Action to prioritise/emphasise OpenTofu support.
• Bump up character limits of TF output (51200 → 66000) and format diff (10240 → 12000).
• Set default values for boolean inputs to reduce usage ambiguity.

Fixed

• Support -or-create flag for more appropriate TF workspace creation via CI.

Deprecated

• Explicit requirement on defining cli_uses input in favour of assuming it automatically from the prior TF-setup step with the wrapper enabled.

Secured

• Document best practices for using 3rd party GitHub Actions in a secure manner.
• Support v10.X and above.
