Anki 2.1.50 brought a change to the WYSIWYG note editor. Previously,
pressing `Control+b` or the `Bold text` button wrapped the selection in
a `<b>` tag, and the latest update changed it to `<strong>`, therefore
breaking scripts and styles for newly added notes. This patch adds
support for the new tag in affected templates.
Update the "Japanese Mined Sentences (cyphar)" template to include the
source field (which is now supported by mpvacious). Also rename the
model name to match the actual name I use in Anki (but keep the template
directory name the same).
