GANDIv5: API Key and PAT

[Knight1]

Welcome

• [X] Yes, I'm using a binary release within 2 latest releases.
• [X] Yes, I've searched similar issues on GitHub and didn't find any.
• [X] Yes, I've included all information below (version, config, etc).

What did you expect to see?

A Certificate, at least changed DNS settings on the provider.

What did you see instead?

Errors.

The Gandi Implementation expects an API Key and optionally a PAT (Personal Access Token)

• If you do not supply the API Key: lego errors and exits.

  gandi: some credentials information are missing: GANDIV5_API_KEY

• If you supply a PAT as API Key: API errors.

  acme: error presenting token: unable to get TXT records for domain x.x and name _acme-challenge: 500: request failed: The server has either erred or is incapable of performing the requested operation.

• If you supply both: Lego uses the deprecated API Key.

How do you use lego?

Binary

Reproduction steps

PAT Variable: "GANDIV5_PERSONAL_ACCESS_TOKEN"

Use API Key in PAT Variable OR: Use only PAT Variable.

Version of lego

lego version 4.14.2 linux/amd64

Logs

With new PAT as API Key ```console acme: error presenting token: unable to get TXT records for domain x.x and name _acme-challenge: 500: request failed: The server has either erred or is incapable of performing the requested operation. ``` Without API Key and only "GANDIV5_PERSONAL_ACCESS_TOKEN" ```console gandi: some credentials information are missing: GANDIV5_API_KEY ```

Hello,

The support of PAT will happen in v4.15. v4.14.x doesn't support PAT, so it's expected that PAT doesn't work with v4.14.2.
