Convert Md to ReST to work around issue with translations

[swzCuroverse]

The following files also have internal links that need converting to ReST.

• [ ] src/index.md
• [ ] src/topics/additional-arguments-and-parameters.md
• [ ] src/topics/best-practices.md
• [ ] src/topics/custom-types.md
• [ ] src/topics/expressions.md
• [ ] src/topics/file-formats.md
• [ ] src/topics/metadata-and-authorship.md
• [ ] src/topics/specifying-software-requirements.md
• [ ] src/topics/using-containers.md
• [ ] src/topics/yaml-guide.md

Conversion process:

(1) Convert markdown to rst

pandoc --from markdown --to rst --reference-links src/topics/additional-arguments-and-parameters.md \
    > src/topics/additional-arguments-and-parameters.rst

(2) Change links to be named links (see description below)

vim src/topics/additional-arguments-and-parameters.rst # edit to change the links to be named links
git add src/topics/additional-arguments-and-parameters.rst
git rm src/topics/additional-arguments-and-parameters.md

Note: the links in the output from pandoc need to be adjusted, even with --reference-links. This is the vim step above, and can be done with any editor.

Change the links from this style:

That way the links have a target (cc-by-human) independent of the link text, which will need to change in the translations.

(3) Edit any references to additional-arguments-and-parameters.md to refer to additional-arguments-and-parameters.rst git grep -l additional-arguments-and-parameters.md -- src | xargs sed -i 's/additional-arguments-and-parameters.md/additional-arguments-and-parameters.rst (if the file name is index.md then be careful, as there are many index.md files)

With @kinow 's patch, this is no longer needed
