The presentation software pdfpc [1] (which is handy for latex beamer slides) supports additional notes on the secondary screen provided by *.pdfpc files.
These can be autogenerated from latex documents with the pdfpcnotes package [2], thus should be ignored in a latex project (but not in others where they could have been created manually).

Add Cursive's REPL history file

**Reasons for making this change:**

The file `replstate.xml` contains the history of the Clojure REPL
that Cursive adds to IntelliJ. Obviously that's user-specific,
and not relevant to other users.

**Links to documentation supporting these rule changes:**

This file is not well-documented, but in cursive-ide/cursive#1325,
the Cursive developers state that this is the REPL history file,
and that deleting it is acceptable troubleshooting if it's
causing trouble.

remove extra line

Our typical workflow has JS and related build outputs in the `build` directory.

Most users are on new SDKs, so we don't have to worry about these ignores.
Most users don't generate docs locally. If they do, it's easy to add the entry to their .gitignore later.
