Use myext_pi1 instead of my_ext_pi1

[sypets]

On the TCEFORM page there are several examples for setting properties in Flexforms. Usually "my_ext_pi1" is given, but this should rather by "myext_pi1".

Resolves: #403

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-11.5 11.5
# Navigate to the new working tree
cd .worktrees/backport-11.5
# Create a new branch
git switch --create backport-406-to-11.5
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 361528451ff2d2799cab78674c40b0cdd5410004,64d69f40a968c525dafe0626529da8b59187e13b,d20fab56c2bacd673a04f1f0a7aa48967a0aa232,33d31a9356c3b498037d1b667be3fec032d89ebe
# Push it to GitHub
git push --set-upstream origin backport-406-to-11.5
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-11.5

Then, create a pull request where the base branch is 11.5 and the compare/head branch is backport-406-to-11.5.

@brotkrueml I accidentally left the section Documentation/UsingSetting/PageTSconfig.rst in here. I noticed afterwards, there is already a description in TCEFORM at the top of the page.

I will add another PR to remove it again. Sorry.
