saltycrys b409cdece5 Improve error message 2
Electric Boogaloo

The long backtrace has been moved into a `<details>` HTML element, as suggested
by @B0pol. To make the error still visible it has been added to the top under
`Title:`. This also encourages informative issue titles.

# InfoExceptions are for displaying information to the user.

# An InfoException might or might not indicate that something went wrong.
# Historically Invidious didn't differentiate between these two options, so to
# maintain previous functionality InfoExceptions do not print backtraces.
