Subject: [PATCH] * lisp/textmodes/markdown-ts-mode.el: More ts-modes for code
 blocks.

(markdown-ts--code-block-language-map): Add more aliases.
(markdown-ts-code-block-source-mode-map): Add more mappings
for existing core ts-modes.
(markdown-ts--convert-code-block-language):
Check 'lang-string' with 'symbolp'.  Check 'mode' with 'fboundp'.

(cherry picked from commit f68482cbc047925d22acf687b814cb94dd7b5bf0)
