Add option to select render profile

In the Quarto project profiles documentation, when we have two environment files named _quarto-advanced.yml and _quarto-production.yml, we gain the capability to render a document under either a single profile or multiple profiles using the following commands:

# Render a single profile via command line
quarto render --profile advanced
quarto render --profile production

# Render with multiple profiles via command line
quarto render --profile advanced,production

However, only the default set in _quarto.yml is being used.

Would it be possible to add a way to specify or select the Quarto profile to build from when using the click-to-render button in VS Code?

Start with the Quarto project profiles documentation and the VS Code click-to-render behavior described in the issue. Compare the existing default from _quarto.yml with the command-line --profile advanced,production examples. Done means a user can select a profile or profile combination when using the VS Code render button, instead of always using the default.
