feat: show exact python interpreter to the agent in IPython and Bash (#3448)

* try to fix pip unavailable * update test case for pip * force rebuild in CI * remove extra symlink * fix newline * added semi-colon to line 31 * Dockerfile.j2: activate env at the end * Revert "Dockerfile.j2: activate env at the end" This reverts commit cf2f5651021fe80d4ab69a35a85f0a35b29dc3d7. * cleanup Dockerfile * switch default python image * remove image agnostic (no longer used) * fix tests * simplify integration tests default image * add nodejs specific runtime tests * update tests and workflows * switch to nikolaik/python-nodejs:python3.11-nodejs22 * update build sh to output image name correctly * increase custom images to test * fix test * fix test * fix double quote * try fixing ci * update ghcr workflow * fix artifact name * try to fix ghcr again * fix workflow * save built image to correct dir * remove extra -docker-image * make last tag to be human readable image tag * fix hyphen to underscore * run test runtime on all tags * revert app build * separate ghcr workflow * update dockerfile for eval * fix tag for test run * try fix tag * try fix tag via matrix output * try workflow again * update comments * try fixing test matrix * fix artifact name * try fix tag again * Revert "try fix tag again" This reverts commit b369badd8cccf4a526e36d27eafb77ea2d32f6be. * tweak filename * try different path * fix filepath * try fix tag artifact path again * save json instead of line * update matrix * print all tags in workflow * support only streaming diff logs from the runtime client * remove strip from log line to fix indentation * get py interpreter for jupyter * rstrip to remove newline on the rightside for logging * fix blocking issue for stream logs * set python interpreter path in bash ps1 * update testcase for jupyter py interpreter path * remove accidentally added changes * remove accidentally added changes * only print dockerfile when debug * add docs * remove extra tests that weren't supposed to be in this pr * add back missing test * revert * make LogBuffer synchronous to fix hang in integration tests * fix integration tests * Update opendevin/runtime/client/client.py Co-authored-by: Engel Nyst <enyst@users.noreply.github.com> * fix test case * fix integration tests * change deque to list * update integration tests * rename test runtime * fix docs * rename opendevin to openhands in tests --------- Co-authored-by: tobitege <tobitege@gmx.de> Co-authored-by: Graham Neubig <neubig@gmail.com> Co-authored-by: tobitege <10787084+tobitege@users.noreply.github.com> Co-authored-by: Engel Nyst <enyst@users.noreply.github.com>
