cache only submodules in tools/

[dhalbert]

Based on 78aca07.

Cache only submodules in tools/, not the whole directory.

List is from:

$ ag "path = tools" --nonumbers .gitmodules |sort
	path = tools/adabot
	path = tools/bitmap_font
	path = tools/huffman
	path = tools/python-semver
	path = tools/Tecate-bitmap-fonts
	path = tools/uf2
	path = tools/usb_descriptor

Directories are allowed here. Only the submodule paths are fed to actions/cache.

Following line does the conversion:

circuitpython/.github/actions/fetch_submodules/action.yml

Line 41 in 72981cf

echo $(cut -d ' ' -f 2 submodule_status) | echo "submodules=[\"$(sed "s/ /\", \"/g")\"]" >> $GITHUB_OUTPUT

From the logs:

Do you understand why @tannewt found 78aca07 necessary, then? He saw a build fail that seemed to be due to caching an old version of something (not a submodule) in tools/

[tannewt]

It was an older version of the caching code. Perhaps this new version works ok.

[dhalbert]

aha, ok, I'll close this for now, then
