docs: add two more amend commits to simulate temporary amend commits

sharing.rst made reference to temporary amend commits and used them to
demonstrate that hidden commits are not exchanged. Nowadays, evolve doesn't
create such commits, but it still makes sense to show how they are handled
during the exchange process. So let's add two more amend commits, one for each
repo. This way the guide doesn't have to be updated too much, but doesn't lose
this important detail of working with evolve.

Unfortunately, this means that tons of hashes change, but it's better than to
have figure 4 demonstrate absolutely nothing.

Temporary amend commits were removed from test-sharing.t in 06844693bb21,
but sharing.rst continued using them for demonstration purposes. It might've
been better to replace at least some of the temporary amend commits by extra
amends back then, but oh well.

Check that topic without any parent does not crash --list

  $ hg up other

'hg stack' list all changeset in the topic

Test "t#" reference

  $ hg up s2

  $ hg up foo

Case with some of the branch unstable
-------------------------------------

  $ echo bbb > ddd
  $ hg commit --amend
  2 new orphan changesets
  $ hg log -G

  $ hg up s2

Also test the revset:

  $ hg log -r 'stack()'
  2 foo {} draft c_c
  6 foo {} draft c_d
  4 foo {} draft c_e
  5 foo {} draft c_f

Case with multiple heads on the topic
-------------------------------------

Make things linear again

  $ hg rebase -s 'desc(c_e)' -d 'desc(c_d) - obsolete()'
  rebasing 4:4f2a69f6d380 "c_e"
  rebasing 5:913c298d8b0a "c_f"
  $ hg log -G
  o  8 foo {} draft c_f
  |
  o  7 foo {} draft c_e
  |
  @  6 foo {} draft c_d
  |
  o  2 foo {} draft c_c
  |
  o  1 other {} public c_b
  |
  o  0 other {} public c_a
  

Create the second branch

  $ hg up 'desc(c_d)'
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo aaa > ggg
  $ hg add ggg
  $ hg commit -m c_g
  created new head
  (consider using topic for lightweight branches. See 'hg help topic')
  $ echo aaa > hhh
  $ hg add hhh
  $ hg commit -m c_h
  $ hg log -G
  @  10 foo {} draft c_h
  |
  o  9 foo {} draft c_g
  |
  | o  8 foo {} draft c_f
  | |
  | o  7 foo {} draft c_e
  |/
  o  6 foo {} draft c_d
  |
  o  2 foo {} draft c_c
  |
  o  1 other {} public c_b
  |
  o  0 other {} public c_a
