docs: Fix a few typos

There are small typos in:
- src/flask_debugtoolbar/panels/profiler.py
- src/flask_debugtoolbar/static/codemirror/mode/rst/rst.js
- src/flask_debugtoolbar/static/codemirror/mode/xquery/xquery.js
- src/flask_debugtoolbar/static/js/jquery.tablesorter.js

Fixes:
- Should read `second` rather than `secound`.
- Should read `preceded` rather than `preceeded`.
- Should read `initial` rather than `inital`.
- Should read `divided` rather than `divded`.
- Should read `debugging` rather than `debuging`.
- Should read `convenience` rather than `conveinence`.
- Should read `capabilities` rather than `capabilitys`.
