add test to test all the flag types

…n WSL (#3132)

There's a complaint that this results in duplicate PATH entries in nested shells, will deal with that separately

`shell` does not fall through to `local`, and `local to `global`.

…sion (#3134)

Requested in #2680
for deployments with a stock `.pyenv-version` that can use any
of a number of Python versions
and for compatibility with `uv`.

* Support `pyenv local --force`
* Support `pyenv-version-file-write --force`
* Support `pyenv version-name --force`
* Ignore missing versions when searching for executables
* Display "commmand not found" even when there are nonexistent versions

* exec.bats: replace `python` and `rspec` with something that doesn't exist globally, either
in Ubuntu Github CI, `python` exists globally

Addendum to #3134 as per #3134 (comment)
