feat: expose description field in component entities

[jvallesm]

Because

• Component page includes a short description of the component.
• operator and connector descriptions were added / updated to use the imperative tense

This commit

• Includes the latest version of protogen-go, which exposes the description field. This will be automatically loaded from definitions.json
• Adds a minor optimization that sets the capacity component list slices, avoiding potential reallocations as the list grows.
• Updates the compogen readme template to use the descriptions in imperative tense.
