Add open_recent option to VS Code desktop

[code-asher]

Together with coder/vscode-coder#272 closes coder/vscode-coder#241

This also (accidentally) fixes what I would imagine is a bug where if there is no folder, it would exclude the URL.

I looked through what runTerraformApply was doing to understand the setup – I think this looks good. Just had a question about what one of the tests was testing for

[Parkreiner]

Making sure I understand: is the point of this test to make sure that open_recent gets serialized into the URL as openRecent?

[code-asher]

Yup exactly! Just making sure setting various options results in being added to the URL correctly.

[code-asher]

Admittedly the test naming could be better, I went with a adds <option name(s)> pattern.

@code-asher this will only work when using the VS Code desktop module. Do we need to do something to also support this with the Coder built-in VSCode desktop button?

I asked the same question here: coder/vscode-coder#241 (comment)

I am not sure if we have any way to customize the built-in button so I think we would have to either make this the default or add options for this, but I feel like we should encourage folks to use the module anyway.

[code-asher]

We decided to make openRecent the default for the built-in app. I think that makes sense, since you cannot configure folder for that one anyway (it always uses the agent directory, I believe).
