Cody: Fix inline-assist files behavior on fixup

[abeatrix]

Close: #51993

Issue

When starting a fixup task from Cody Inline Assist with multiple files open in the editor, each open file will get a new code lens and the fixup replacement will be performed in the file that the user last focused on.

Causes

• During the fixup step, we are calling the active editor with vscode.window.activeTextEditor which could include editors that have other files opened without the original comment thread where we call the fixup job
• Code lenses are generated on all open files and it gets called everytime we make changes to a text document (any text document)

Solution

Here are the changes introduced in this PR as potential solutions:

• Activate code lenses on files that match the filePath from the comment thread: e.document.uri.fsPath !== this.thread?.uri.fsPath
• Get editor info using the file path of the file that we called fixup from

Test plan

Run debug and start extension locally:

• open two different files side by side in your editor and start a fixup job in one of them

Expected Behavior:

• Only the file where you call the fixup job from will be updated accordingly
