Show snippet error update to the user
What does this MR do?
At the moment, we're implementing several checks when a user pushes a commit. Some of these checks, raises comprehensive messages that can be useful for users, like if the snippet content size is higher than the limit, or whether the number of files is higher than the allowed limit.
Instead of showing a generic message, it can be useful for users to see this message. Besides, it can be more useful to debug problems later from our side.
Does this MR meet the acceptance criteria?
