Some more enhancements to Prism based syntax highlighting

[sivaraam]

Right now the bundled Prism file to support syntax highlighting (cf. #490) supports these: markup (covering html, xml, svg, mathml, ssml, atom, rss), CSS, C-like, JavaScript (js), C, C++ (cpp), Bash (sh, shell), Diff, Git, Go, JSON (webmanifest), Makefile, Perl, Python (py), Ruby (rb), and YAML (yml).

The following plugins are also bundled Autoloader and File Highlight.

I think we might be able to strip the supported languages significantly to only those that are used in the repository. This would reduce the bundle download size.

A few other things to check:

• It seems the Prism header from the artifact downloaded from the website has been removed. I think we can retain that.
• We might need to check if it is possible to achieve the same syntax highlight in the e-mail version of the newsletter @mjaix

Thanks @sivaraam ,
for involving me in this. I can help check which languages are actually used in the repository and report back.

Hi @sivaraam ,

i have checked 138 files some manually and some using Agents , what i have concluded from my search i.e,
languages --> shell/Bash , C , Diff , INI , Python
non-language contents --> Git Commit Graph/Log/Patch Header,Plain Text / Terminal Output / Benchmark

we can use PrismJs for these languages and non-language contents .

if you allow me , I will start working on this and make changes in script/prism.js accordingly.
