refactored in 01df394 but leaving some notes

• Kept regex patterns as new regexp don't support all cases e.g. 1.64.1b0
• Kept the form of cat ... | sed ... | tee ... instead of sed in-place modification for straightforward compatibility with bsd sed (for direct macOS testing without any confusion)
• Sorting and filtering over tag name from gh response is still a thing as they respond with npm prefix which we don't want to use
• Kept github api version in curl for future consistency
