Move endpoints to txt files (#10)

[salvafern]

Explained in #10

Hi @tim-collart

Question coming from EMODnet/emodnet.wfs#139

Would you agree with turning the tables in the README containing the endpoints for WFS etc into csv or other tabulated file format?

Reason:
The most up-to-date place where the endpoints of EMODnet are seems to be this repo. We (me and @maelle ) could not figure out how to get such an updated list from geonetwork (See EMODnet/emodnet.wfs#129 (comment)).

We know that eventually geonetwork will be the best place to get such a list, but for the time being we are struggling to keep up with updated services as we are normally not notified of any change, hence we only get to know via CI/CD errors in the EMODnetWFS repo. Which is quite frustrating tbh.

Proposal:
If you agreed I would suggest one of these ideas to read the csv file with the endpoints

Turn the README into a RMarkdown document (currently plain markdown). Read the file as a data frame and knit to a markdown document.
Use a github action that turns the csv into a markdown table and injects into the README.md with every commit.

Thanks in advance and let me know you agree. Happy to give it a try and do a PR.

• I created a few tab separated txt files added to a new dir data/ with the enpoints.
• I also created a README.Rmd file that can be knitted to the README.md doc. It reads the txt files and prints as markdown tables.
• Whenever an endpoint change, this needs to be done in the txt file and the README.Rmd needs to knitted to README.md. In return, we can read these txt files programatically e.g. in EMODnetWFS

@salvafern I went ahead and added a GitHub Actions workflow that automatically knits the README if README.Rmd or data/ have changes; or with a manual trigger. It's inspired by the one rOpenSci software-review uses https://github.com/ropensci/software-review/blob/main/.github/workflows/main.yml

Since this repository was created before February, things should just work (for later repos, this change https://github.blog/changelog/2023-02-02-github-actions-updating-the-default-github_token-permissions-to-read-only/ means a setting would need to be tweaked to allow GHA to commit)
