patch 9.1.0392: tests: Vim9 debug tests may be flaky

Problem:  tests: Vim9 debug tests may be flaky
          (Shane-XB-Qian)
Solution: Give a few more lines so that line-wrapping won't
          cause a hit-enter prompt

The two tests Run_Test_debug_running_out_of_lines() and
Run_Test_debug_with_lambda() test debugging of Vim script functions.

Depending from what file-path the tests are run, it may cause
line wrapping to occur on the following output:

Entering Debug mode.  Type "cont" to continue.
command line..script
/home/chrisbra/code/vim-upstream/src/testdir/XdebugFunc[15]..function
<SNR>9_Crash

and if the window is too small, this will cause a hit-enter prompt and so
the WaitForAssert() fails, causing failure of the following tests.

So increase the (internal) Vim window by a few more lines, so that even
if line-wrapping occurs, no hit-enter prompts happens and so the tests
can finish.

fixes: #14596
closes: #14691
