[EH] Replace event with tag (#3937)

We recently decided to change 'event' to 'tag', and to 'event section'
to 'tag section', out of the rationale that the section contains a
generalized tag that references a type, which may be used for something
other than exceptions, and the name 'event' can be confusing in the web
context.
