Setting as draft because I'm not sure this is desired behavior. Nobody has complained about this so maybe best to not create the PR and just skip the crash. |

I reviewed the repository where I observed this, and repo maintainer was happily merging dependabot PRs before this bug appeared. So I say let's go with this approach and restore those PRs. |

If a library has both a pyproject.toml file and a standard
requirements.txt file, we'd end up using the `:widen` strategy for the
dependencies in the `requirements.txt` file and eventually crashing with
an error like the following:
```
/home/dependabot/dependabot-core/common/lib/dependabot/update_checkers/base.rb:266:in `block in preferred_version_resolvable_with_unlock?': undefined method `[]' for nil:NilClass (NoMethodError)
updated_requirements.none? { |r| r[:requirement] == :unfixable }
^^^^^^^^^^^^^^
from /home/dependabot/dependabot-core/common/lib/dependabot/update_checkers/base.rb:266:in `none?'
from /home/dependabot/dependabot-core/common/lib/dependabot/update_checkers/base.rb:266:in `preferred_version_resolvable_with_unlock?'
from /home/dependabot/dependabot-core/common/lib/dependabot/update_checkers/base.rb:249:in `numeric_version_can_update?'
from /home/dependabot/dependabot-core/common/lib/dependabot/update_checkers/base.rb:199:in `version_can_update?'
from /home/dependabot/dependabot-core/common/lib/dependabot/update_checkers/base.rb:44:in `can_update?'
from bin/dry-run.rb:709:in `block in <main>'
from bin/dry-run.rb:661:in `each'
from bin/dry-run.rb:661:in `<main>'
```
I think the crash happens because the requirements.txt file updater does
not supoort the `:widen` strategy. So my fix is to fallback to
`increase` in this case, since requirements.txt files usually include
pinned dependencies so widening probably doesn't make much sense there.

I discovered this issue while wrapping up #5661. However, the issue is already there so I think it makes sense to extract it to its own PR.
