Verify setup for ohw-tutorials submodule

@abkfenris:

I'm copying your comment from https://github.com/oceanhackweek/oceanhackweek.github.io/pull/261#issuecomment-1650373948

The tutorials are linked via a git submodule which is defined here, but there is an incantation for adding them that I don't remember at the moment, but here is the PR when I set things up that way.

The .gitmodules setup seems straightforward. Once we have a tutorials OHW23 branch, we'll copy and adapt the ohw22 block to this:

[submodule "ohw23/tutorials"]
	path = ohw23/tutorials
	url = https://github.com/oceanhackweek/ohw-tutorials.git
	branch = OHW23

The incantation you referred to seems to be the

with:
    submodules: true

blocks in workflows/check_sphinx_build.yml and workflows/deploy-docs.yml. If so, it looks like nothing more needs to be done.

Does that look right?

.gitmodules から始め、既存の ohw22 ブロックを PR 199 と比較してから、.github/workflows/check_sphinx_build.yml と .github/workflows/deploy-docs.yml を確認します。OHW23 tutorials のサブモジュールと、サブモジュールが有効になっている両方の workflow ブロックで十分かを検証します。設定を確認するか、不足している変更を文書化できれば完了です。
