DX-780: Avoid guessing common words/module names

[blast-hardcheese]

Why

pypi permits packages with extraordinarily common names (utils) as well as misconfigured packages (gardener-cicd-base, in this case, pollutes site-packages with util.py, model/, and ci/, among others)

What changed

I crossreferenced top-level packages discovered from pypi packages with /usr/share/dict/words then hand-pruned down to what I believe is a sensible list of names that can be common internal module names for projects, as well as excluding names that are popular pypi packages.

If there are any incorrect or missing entries, we can tune this over time, this is just trying to prevent import util guessing random stuff.

• Add a wordlist
• Delete guesses based on inclusion in the wordlist

Test plan

Before

$ echo $'import util\nimport utils' > main.py
$ upm guess --force
gardener-cicd-base
utils

After

$ echo $'import util\nimport utils' > main.py
$ upm guess --force
$
