Vault unsealing process link doesn't actually have the process

[Nobuto Murata]

The doc has a paragraph as:
https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/install-openstack.html#vault
> Vault must now be initialised and unsealed. The vault charm will also need to be authorised to carry out certain tasks. These steps are covered in the vault charm documentation. Perform them now.

"the vault charm documentation" is linked to:
https://charmhub.io/vault

But the charmhub page nowadays doesn't reveal charm's README but only a brief description as follows.

> a tool for managing secrets
>
> Vault secures, stores, and tightly controls access to tokens, passwords, certificates, API keys, and other secrets in modern computing. Vault handles leasing, key revocation, key rolling, and auditing. Through a unified API, users can access an encrypted Key/Value store and network encryption-as-a-service, or generate AWS IAM/STS credentials, SQL/NoSQL databases, X.509 certificates, SSH credentials, and more.

I think we need either:
1. the charmhub page should reveal the whole unsealing process
or
2. the charm-guide linked to the README directly
https://github.com/openstack/charm-vault/blob/master/src/README.md#post-deployment-tasks
