Update Cecil to 0.11.2

Closes #1616

FYI, this PR unblocks GitHub Desktop for Surface Pro X and VSCode for Surface Pro X. Looking forward excitedly to this minor change being committed!

If the team considers the upgrade from 0.9.6.1 to 0.11.2 "too risky", it is also possible to upgrade to 0.10 as it seems to be included in that version already.

@JayBeavers I'm so confused, VS Code rejected Squirrel.Windows long long ago, are you saying they switched back to it?

[JayBeavers]

Pardon, I may have gotten confused by the cross-project discussion between similar needs of Github Desktop and VS Code. I went and looked back at the arm64 support threads for VSCode and I don't see the mention of the squirrel dependency.

Just an overeager dev who loves his Surface Pro X and wants native binaries for core tools :-)

Ah, I see. desktop/desktop#9691 was linked to the thread on supporting arm64 with VSCode (microsoft/vscode#33620)
and I didn't pick up from the UI that this was a work item on github desktop, not on vscode.
