fix: broken link in readme

[Lee-WonJun]

• The section name custom-client-configuration has been changed to Configuration.

• It seems that each part was also modified, probably due to spaces or emojis. At the very least, navigation doesn’t work in my Edge/Chrome browser.

The link is not broken for me? It will route to the subheading

It seems that the custom-client-configuration subheading has been removed — or am I mistaken? When I click the link, it doesn’t navigate to the specific section as expected.

Hi @Lee-WonJun, you are right, it also does not work for me.

I believe GitHub has a different way of interpreting the anchors (the links that connect the sections) than VS Code or other IDEs.

Some other anchors (in the quick navigation for example) are also broken for me on the deployed GitHub but work properly when testing locally. I will fix the remaining anchors when I get home and then we can merge this PR. Thank you for bringing this to our attention!

I created a dummy GitHub repository to test these changes, and the anchors were properly fixed. Good to merge
