quarto preview in a terminal with a venv: increase wait time to 5s

[cscheid]

This attempts to work around vscode clobbering the preview command; recent versions appear to inject shell commands after quarto preview started, which completely breaks the preview command. The 5s timeout was not determined with any level of rigor, but does consistently solve the problem in my environment.

This is working well with venv-driven rendering in Positron, with any of the configurations I am using:

I will say that I couldn't reproduce the original problem with VS Code 1.118.1 and the released Quarto extension. Does that surprise you?

Can you add a line to the CHANGELOG for this update?

I'm not surprised, because this slipped by us. I could only manage to reproduce it by having my shell enable a venv by default.

Sorry, the changelog entry is there now. (My previous push attempt had failed because of the github outage and I didn't notice.)

Added a comment explaining that this timeout is a magic number found with trial & error. Will merge once tests pass
