Subject: [PATCH] fix(data): correct XML closing tag insertion
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`nxml-slash-auto-complete-flag` inserts the rest of the closing tag when
`</` is inserted, but smartparens also defines `(sp-local-pair "<" ">")`
for `sp--html-modes`, so two `>` are inserted for closing tags. Apply
the upstream developer’s suggested fix.

Fix: https://github.com/doomemacs/doomemacs/issues/6331
Ref: https://github.com/Fuco1/smartparens/issues/397
