🚀 Feature: Reusable layout (template)

[Swahjak]

🔖 Feature description

Add reusable layouts that can be used to make templating less repetitive and easier to maintain (not having to edit all templates when something, like a company phone number, changes.

🎤 Why is this feature needed ?

In many cases, especially for e-mail, you re-use many components in an e-mail. While having access to MJML (https://github.com/novuhq/novu/issues/1792) would help. It still leaves us with repetitive work to recreate headers and footers for each template. Postmark solves this issues by allowing users to define a 'layout' that contains a placeholder {{{ @content }}}, which can then be used when creating a template. The contents of the template will be replace the {{{ @content }}} placeholder.

✌️ How do you aim to achieve this?

Add a section "Layouts" in "Settings" in which one (or more) layouts can be created. Layouts can then be used when creating templates. When a layout is used, the contents of the template are placed in the layout using the {{{ @content }}} placeholder.
