Fix #121: Add REPL to weakdepends in temp Manifest

[pjaap]

This should fix #121

Steps to reproduce the previous failure:

$ git clone https://github.com/pjaap/TestPackage.jl # simple package with a single unit test
$ julia
] activate @v1.11
] add TestReports
] activate TestPackage.jl
julia> using TestReports
julia> TestReports.test("TestPackage") # crash

Adding TestReports in the TestPackage environment does not create a crash.

This may temporarily fix the issue but if some other stdlibs adds a weakdep or something this package will break again.
