Governance Action metadata builder error handling

[MSzalowski]

Why

As someone who wants to input background information about a governance action

I want the UI to warn me when there is an error

So that I do not create something unusable

What

Given that I have input something into the metadata builder that does not comply with CIP-108 or is not in the correct format

When I attempt to proceed to the next page

Then I will be prevented from doing so and be told why and where there is an error

Link to figma

DoD

There is error handling to ensure that the information being entered into the metadata builder is in a format that can be developed into metadata.

Done with #445

@MSzalowski Valid public available Info - file Cannot be found, error message 'The URL You Entered Cannot Be Found'

[MSzalowski]

It is related to #30 as it introduces the limitation of allowed domains - I am investigating the potential solution

[MSzalowski]

Closed with #480

OK when:

• valid URL and file matches
• not reachable content detected
• not matching metadata file detected fine
