FR: Add support for pattern substitutions

[ofek]

I'm seeing things like this frequently:

# Replace relative paths to images with absolute paths
long_description = re.sub("website/homepage/", "https://raw.githubusercontent.com/gradio-app/gradio/main/website/homepage/", long_description)
long_description = re.sub(r"demo/([\S]*.gif)", r"https://raw.githubusercontent.com/gradio-app/gradio/main/demo/\g<1>", long_description)

maybe:

[[tool.hatch.metadata.hooks.fancy-pypi-readme.substitutions]]
find = "website/homepage/"
replace = "https://raw.githubusercontent.com/gradio-app/gradio/main/website/homepage/"

[[tool.hatch.metadata.hooks.fancy-pypi-readme.substitutions]]
find = 'demo/([\S]*.gif)'
replace = 'https://raw.githubusercontent.com/gradio-app/gradio/main/demo/\g<1>'

Yeah this has been on my todo list since someone asked about https://github.com/twisted/twisted/blob/eda9d29dc7fe34e7b207781e5674dc92f798bffe/setup.py#L19-L24

pydantic just switched and would use this pydantic/pydantic#4473 (comment)

history = (THIS_DIR / 'HISTORY.md').read_text(encoding='utf-8')
history = re.sub(r'#(\d+)', r'[#\1](https://github.com/pydantic/pydantic/issues/\1)', history)
history = re.sub(r'( +)@([\w\-]+)', r'\1[@\2](https://github.com/\2)', history, flags=re.I)
history = re.sub('@@', '@', history)

long_description = (THIS_DIR / 'README.md').read_text(encoding='utf-8') + '\n\n' + history

[hynek]

BTW any idea what that @@, @ is about? I can't find any @@ in their history.md?

People do weird things 🤷‍♂️
