Update guides to include frontend security advices, practices and procedures

Overview of the Feature Request

When including the SECURITY.md file, based on the same as the Dataverse core repository, I realized that it will be necessary to add security-related guides for the Frontend, since at the moment we are referencing the general guidelines of Dataverse:

• https://guides.dataverse.org/en/latest/installation/config.html#securing-your-installation
• https://guides.dataverse.org/en/latest/developers/security.html

For including these security-related guides for the Frontend we need to close #26 first.

What kind of user is the feature intended for?

Dataverse frontend developers

What inspired the request?

• Including SECURITY.md for #2

What existing behavior do you want changed?

N/A

Any brand new behavior do you want to add to Dataverse Frontend?

N/A

Any related open or closed issues to this feature request?

• #2
• #26

Start by reviewing the repository's SECURITY.md context and issue #26, which this request says must be completed first. Use the linked Dataverse installation and developer security guides as references, then add frontend-specific security guidance for Dataverse frontend developers; done means the requested guides are present and no longer rely only on the general Dataverse references.
