Subject: [PATCH 1/2] Replace CompatHelper with Dependabot for Julia compat
 updates

Dependabot now supports the `julia` package ecosystem, so use it to keep
the `[compat]` entries of `Project.toml` and `docs/Project.toml` up to
date instead of the CompatHelper workflow. Updates are grouped into a
single PR, mirroring the setup in Distributions.jl.

Add a `[workspace]` section listing `docs` so that Pkg (on Julia 1.12+)
and Dependabot resolve the package and the docs environment together.
Dependabot then only needs the root directory. Older Julia versions
ignore the section.

Subject: [PATCH 2/2] Require WeakRefStrings 1.4 or later in tests

With the docs workspace, the test environment on Julia 1.12+ resolves
InlineStrings 2, which WeakRefStrings 1.4 does not allow. The resolver
then falls back to WeakRefStrings 1.3, which uses the removed
`Base.memhash_seed` and errors on current Julia. Allow WeakRefStrings 2
and exclude the releases before 1.4.
