Fix an incorrect autocorrect for Style/MapToHash with Layout/SingleLineBlockChain

[koic]

This PR fixes an incorrect autocorrect for Style/MapToHash with Layout/SingleLineBlockChain, which makes the following syntax error occur:

$ cat example.rb
obj.map { |i| foo(i) }.to_h
   .bar

$ bundle exec rubocop -A example.rb --only Style/MapToHash,Layout/SingleLineBlockChain
Inspecting 1 file
F

Offenses:

example.rb:1:5: C: [Corrected] Style/MapToHash: Pass a block to to_h instead of calling map.to_h.
obj.map { |i| foo(i) }.to_h
    ^^^
example.rb:1:23: C: [Corrected] Layout/SingleLineBlockChain: Put method call on a separate line if chained to a single line block.
obj.map { |i| foo(i) }.to_h
                      ^^^^^
example.rb:3:4: F: Lint/Syntax: unexpected token tDOT
(Using Ruby 3.3 parser; configure using TargetRubyVersion parameter, under AllCops)
   .bar

Another example for the false-negative on the Style/MapToHash:

hsh = [['a', '1'], ['b', '2']]
# hsh = nil

# bad
hsh&.map { |k, v| [k, v] }&.to_h

# good
hsh&.to_h { |k,v| [k, v] }

That issue is different from the intended fix of this PR, so I've opened a separate PR #12408. Thank you.
