gh-37447: Replace bootstrap-conda by grayskull and update conda lock files
    
<!-- ^^^^^
Please provide a concise, informative and self-explanatory title.
Don't put issue numbers in there, do this in the PR body below.
For example, instead of "Fixes #1234" use "Introduce new method to
calculate 1+1"
-->
<!-- Describe your changes here in detail -->

Using the metadata added in #37446,
we automatically generate the conda environment files. This no longer
makes any reference to the `conda.txt` files contained in sage-the-
distribution. Thus sage-on-top-of-conda is now completely independent of
sage-the-distribution (only relying on information specified by sage-
the-library). In particular, after this PR is merged the `conda.txt`
files could be deleted from sage-the-distribution.

In particular, we no longer need to maintain the mapping of pypi
packages to conda packages but instead can rely on the offical mappings
maintained by the conda team (https://github.com/regro/cf-graph-
countyfair/tree/master/mappings/pypi).

To test:
```
pip install grayskull conda-lock
python tools/update-conda.py
```

The updated conda files are committed here as well.

Moreover, the `environment-dev` files have been deleted as there was
only little difference between these files and some people rightfully
complained that having too many files in the root folder is distracting.

As a byproduct, this fixes #34626.
