test(plugin/pack_spec): handle pcall path truncation #36143
Problem
In `vim.pack` the source of any errors is included in the `update`
buffer from lua's `pcall` method. Since the full path is known it is
replaced in the unit test by the string `VIM_PACK_RUNTIME`. The issue is
that `pcall` does not necessarily include the full path, it instead uses
the `lua_Debug` `short_src` value which can be truncated. This means
depending on where you've cloned the repo locally the test can fail.
Solution
Change the replacement pattern for the traceback to be more generic and
handle any path prefix, not just the value of `vim.env.VIMRUNTIME`.
