Pattern matching for special files ignores trailing slashes

[ile-24556]

Describe the bug

The pattern matching for .chezmoiignore and .chezmoiremove ignores trailing slashes in a pattern.

To reproduce

Here I only mention about .chezmoiignore:

1. Prepare files:

   mkdir -p ~/d1/d2
   touch ~/d1/p ~/d1/d2/q

2. Add files:

   chezmoi add ~/d1

   $ chezmoi managed | grep '^d1'
   d1
   d1/d2
   d1/d2/q
   d1/p

3. Add the following pattern to .chezmoiignore:

   d1/?*/

4. List managed files:

   chezmoi managed | grep '^d1'

Expected behavior

chezmoi ignores d2 (and its content q):

d1
d1/p

Output of command with the --verbose flag

Actually, it ignores everything under d1 including file p:

$ chezmoi --verbose managed | grep '^d1'
d1

Output of chezmoi doctor

Additional context

It was derived from #4636.

I think some people (including me) confuse it with .gitignore’s pattern matching. Additional documentation may be helpful.
