fix: add new bzl_library for 'ty' with dependencies (#675)

otherwise loading it is an error for stardoc

feat: Add cppcheck lint aspect (#617)

Add `cppcheck` as `lint` aspect as per
#569.
A local test can be ran using: `cd example; bazel lint //src:hello_cc`
The aspect supports human readable output and `xml` output, e.g.
`cd example; bazel build //...
--aspects=//tools/lint:linters.bzl%cppcheck
--output_groups=rules_lint_xml`

### Changes are visible to end-users: yes

- Searched for relevant documentation and updated as needed: yes
- Breaking change (forces users to change their own code or config): no
- Suggested release notes appear below: yes

"Add cppcheck linter"

### Test plan

- Manual testing: `cd example; bazel build //...
--aspects=//tools/lint:linters.bzl%cppcheck
--output_groups=rules_lint_xml`: This will produce following output:
```

Update formatting.md

fix: need newer publish-to-bcr

The 1.10.1 release has missing interpolation in docs_url

fix: add docs_url

fix: Shell formatter finds files without extension (#622)

This lets `shfmt` format shell scripts identified only by their shebang
but without any extension.

Closes #549

### Changes are visible to end-users: yes

- Breaking change (forces users to change their own code or config): no
but...

The formatter will now format more files in the users' repository.

The "Shell" run is also slower.

For reference, it runs in about 10 seconds on my laptop in the
https://github.com/Checkmk/checkmk repository. I would say that it is
acceptable. For comparison, formatting our (unfortunately closed-source)
C++ code takes 5 sec.


### Test plan

- Covered by existing test cases: `shfmt` is already supported
- New test cases added: Copied a `hello.sh` to `hello_sh` (no extension)
in the example directory and made sure it's picked up by the formatter.
- Manual testing: I also ran `bazel run //:format` with the current
patch in https://github.com/Checkmk/checkmk and it reformatted files
identified only by their shebang

fix: clang-tidy in external modules: use full paths (#628)

Solves #627 

---

### Changes are visible to end-users: yes/no

Should enable the aspect to run on stuff in external modules now.

### Test plan

fix: port ruff fixes from aspect-internal silo (#623)

chore(deps): update to newer rules_buf (#616)

Seems to improve wall time of running formatter

fix: move rules_diff above SNIP

It doesn't need to be in user install instructions.

Fixes #613
