Brings the CI and package setup in line with ChainRulesCore (JuliaDiff/ChainRulesCore.jl#715, JuliaDiff/ChainRulesCore.jl#717) and ChainRules (JuliaDiff/ChainRules.jl#850).

CI

• Replace CompatHelper with Dependabot's julia ecosystem
• Add a typos spell check workflow (and fix the typos it finds)
• Keep the existing test matrix (lts and 1 on Linux, macOS and Windows, native arch), and test pre on Linux with allowed failures instead of in the separate JuliaNightly workflow
• Upload coverage from the CI jobs
• Build the docs in the CI workflow on Julia 1. The separate Documenter workflow only ran on pushes to the non-existent master branch, so the dev docs were never deployed from main
• IntegrationTest: run on main (was master), add cache and permissions, and test the downstream packages in a temporary environment
• Add concurrency and permissions settings, and update action versions (no more @latest/@v1/@v2 pins)

Julia setup

• Require Julia 1.10 and drop obsolete version checks in the tests
• Remove the Compat dependency (only is in Base) and add compat entries for stdlibs
• Move the test dependencies to test/Project.toml and set up a workspace with the test and docs environments, using [sources] instead of Pkg.develop and the checked-in docs/Manifest.toml
• Update Documenter to v1. The doctests had been failing silently under Documenter 0.27. They now ignore Test Summary tables, which differ between makedocs and doctest() and across Julia versions, and the deliberately failing test_rrule example (random output) is no longer doctested
• Only import Test.eval_test on Julia < 1.13: since JuliaLang/julia@d934b03 (1.13.0-DEV.300) it is replaced by eval_test_comparison and eval_test_function, and the unconditional import printed "WARNING: Imported binding Test.eval_test was undeclared at import time". The import is still required on older versions, where the code generated by @test_msg calls eval_test unqualified
• Bump the version to 1.13.2

Local checks

• Pkg.test() passes on Julia 1.10.12 and 1.13.1, without the eval_test warning on 1.13
• docs/make.jl and doctest(ChainRulesTestUtils) pass on Julia 1.13.1; doctest also passes on 1.10.12
• typos reports nothing
