Links in documentation are not legible (accessibility issue)

[patricknelson]

For example, this paragraph has a link (see https://openswoole.com/docs/get-started-swoole#try-it-with-docker):

Similar issue exists in the dark theme, except the color is far too dark and instead starts to blend in with the background color:

My apologies if this isn't the right repository. I looked for a repo that contained the docs but it was not easy to find (no edit links in the docs and I didn't notice where the docs were managed, if they're on github). Just happened upon this issue when trying to read through the docs for the first time and found them very difficult to go through due to the issues with links.
