readthedocs builds are failing for latest 8.0.0 builds

From readthedocs logs:

I think this may be due to the latest ci_fetch_deps.py changes.

Tagging @microdev1

[microdev1]

The following changes are needed:

- python tools/ci_fetch_deps.py docs HEAD
+ python tools/ci_fetch_deps.py build-doc

Add the following if tags are needed.

git fetch --no-recurse-submodules --shallow-since="2021-07-01" --tags https://github.com/adafruit/circuitpython HEAD
git fetch --no-recurse-submodules --shallow-since="2021-07-01" origin HEAD
git repack -d

git repack -d

curious why it's worth spending time repacking when not many git operations will be done subsequent to this.

It exits immediately with the message Nothing new to repack.

I am not sure we need tags for the RTD build. I don't know how to check that without proposing just the first change and then merging it.

@microdev1 Thank you -- that one-line fix worked:
