feat(content): add asset definitions

[Otijom]

No description provided.

The title
Migration generic assets to asset definitions
Migration generic objects to asset definitions

In the Note box for Create an asset, I'd mention the impossibility to change the System Name after the Custom asset is created due to avoid conflicts in the future.

Below Fields Header:
The fields tab is used to add additional fields and, and hide, or reorder native ones. You can customise them by indicating whether they should be text, URL, date, etc.

Translations
Instead of bullet points, numbered list according top the picture.
On number 4

• one - the singular form of the label
• many - the plural form of the label
• other - the translation that will appear in the list of assets

I'm adding a comment because I'm not sure how to add commits to this PR and to not forget the suggestions whilst I read the PR
