Should fix the current failure that "master" does not exist.
I am a bit curious why master does not exist, maybe the CircleCI
git is set up to use some other default.
Move the branch rename to after the commit, to make sure that
the fact that the branch is empty (and `git branch` also)
cannot influence the result.

It seems the git in the CircleCI environment does not have the
`--initial-branch` option that my local git has, hopefully
`git branch -m` works fine.

The default of git is still "master", so we need to set
`--initial-branch=main` to ensure that we use the name `main`
that is used in the devdoc repository.

Closes gh-18568

* Upload docs to main branch of neps/devdocs

* Update `master` to `main` to be consistent with current state of renaming

* Remove badges from README

* Replace remaining instances of `master` with `main`

* Add back logo

* Fix CircleCI branch checks

* Fix GA branch name

* master->main in issue templates.

* master->main for 2 links to numpy archive.

* Change master to main in NEP 23

For the moment, this requires te use for the development version
of towncrier.

* Upload devdocs and neps after build

* Install numpydoc

* Fix masked array documentation injection

`doc_note` appends a `Notes` section to docstrings, which may lead to
duplicate sections.

* Add deploy key for neps repo

Note that we have to explicitly reset the ~/.ssh/config to only leave
one SSH key

* Only deploy on master branch

* Blow away previous dev docs after each upload

* Add tool to upload files to remote repo

* Remove numpydoc from pip install; it is included as a submodule

* Avoid using invalid escape code

* Rename repo upload tool

* Use check_call to simplify doc pushing tool
