Closes #1186

Sync the following merged pull requests into LTS 1.x:

• fixed syntax error when numpy is in path but IronPython #1185

What type of change is this?

• Sync to LTS branch

Process

The process to create this sync is the following:

• Create a new branch off of the LTS branch for syncs up to current date, e.g. lts-backports/sync-230423
• For each merged pull request that needs to be merged into LTS:
  • Cherry pick ranges of commits (you can use the github commits page of the PR to copy the oldest and newest commit hash): e.g. git cherry-pick "fdc342d15a2908f4b72f437aeb05165eba098920^..f3874fea755ba3c6bdb28fcf33d870c4dbad451e" (see this stackoverflow answer for details)
  • Fix any pending conflicts (using the Conflict editor of vscode seems to be the easiest option.
  • Confirm the cherry pick operation with git cherry-pick --continue
  • Repeat for the next pull request
  • Ensure the CHANGELOG is correct, after cherry picking, the entries might have been added to previous releases instead of the Unreleased section.
• Push the sync branch and create a pull request to the LTS branch

After this PR has been merged:

• Switch to the LTS branch
• Create a new release using invoke release patch and push
• Update doc_versions.txt and versions.json
• Update the cloudflare rules to redirect the previous LTS doc links to the newest
• Create a new issue for the next LTS sync
