[BUG] - Copy-pasted featured images

Description

Too many blog posts have copy-pasted the exact same image under /public/posts/[slug]/, we should delete the copy-pasted images, hoist them up a level or two, and share them across the blog posts. This will require many image file deletions, and for each deletion, an update to the corresponding post's .md(x) file metadata. For example:

Same images:

1. apps/labs/public/posts/Spyder4-variable-explorer/blog_feature_org.svg
2. apps/labs/public/posts/a-second-czi-grant-for-numpy-and-openblas/blog_feature_var1.svg

Okay, if you paid close attention, those two above are not exactly the same, but (a) they are similar enough that we should consider merging them and (b) I'm (99%) sure there are other posts that are using bit-for-bit same images.

Corresponding metadata:

1. Spyder4-variable-explorer.md line 8
2. a-second-czi-grant-for-numpy-and-openblas.md line 8
