These lines don't handle version substitution in a way that retains the valid structure of the table:

As a result, we can unintentionally break the table and make it disappear entirely. It's easily fixed, for example:

#13365

However it would be better to catch before we merge it.

Possible paths:

• Fix the script to make it understand the table better, or
• Add a simple .RST validator for the README.rst to make sure that if we break the table, the CI will complain.
