Ignore dotenv in dart

Add nuget.config file

Add AltiumDesigner.gitignore

Update Coq.gitignore

Add nuget.config file because it contains secret data and should be kept localy

Coq now uses .mlg rather than .ml4 (since https://github.com/coq/coq/pull/8763), so we have to ignore its generated dependency files.  The `native_compute_profile_*.data` files are generated by `Set NativeCompute Profiling` (see https://github.com/coq/coq/pull/950).  Finally `.coq-native` is a directory that may be generated in any subdirectory, not only at top level, so we should not use absolute paths for it.

I added this .gitignore to a project that included a file named CoverageSearchModel.cs, and the file was wrongly ignored.  This change fixes the incorrect use of the range operator on the Coverlet rules.

The problem here was two fold:
1. the folder "/target/" would be top-level of the repo only, it should be "target/" to properly exclude target folders anywhere in the repo
2. the default Rust/Cargo folder when compiling code is "debug/", which gets used perhaps more often that "target/", added that

After running `yarn set version berry` and `yarn install`, the file `.yarn/install-state.gz` is created.

The documentation at https://yarnpkg.com/advanced/qa#which-files-should-be-gitignored mentions that this file should be ignored:

> .yarn/install-state.tgz is an optimization file that you shouldn't have to ever commit. It simply stores the exact state of your project so that the next commands can boot without having to resolve your workspaces again.

The documentation has a minor error; the generated file is `.gz` instead of `.tgz` (source: https://github.com/yarnpkg/berry/pull/998/files#diff-23dd4c2e823c25186f1107e88e962032R201)

Generated files that appear when using 'google_fonts' or other Dart
packages designed as Flutter plugins.

pip generated this folder for a few versions, as part of it's initial
implementation of PEP 517.

pip has not generated this folder for a few versions now, so it should
be OK to remove this from the standard gitignore file.

These generated files were added in https://github.com/coq/coq/pull/745

Projects using QML files generating a temporary qrc file if a qrc file present in the project.

Visual Studio .Net used Win32/ as one of the default output directories for C and C++ projects. Later, when 64-bit support was added to the toolchain (circa 2005), x64/ was used. The Gitignore files include x64/, but not Win32/. The commit adds support for both Win32/ and x64/.

Ignore .dirstamp files from automake used for non-existing directory dependencies.
