Syntax Highlighting regex+format strings (rf)

• Editor name and version: VSCode 1.75.1
• Platform: macOS
• Color scheme: Dark+ (default)
• MagicPython version: 1.1.0
• A sreenshot:
  
• 5-10 lines of surrounding code:

myString = "baz"
MYCONST = "qux"
myDict = {
    "foo": "bar"
}

correctColoring = rf"(?=[\w]+){myString}{MYCONST}[\d]+"

incorrectDictionary = rf"(?=[\w]+){myDict['foo']}[\d]+"
regularFString = f"word{myDict['foo']}number"

This is a followup to #186. After upgrading to 1.1.0, I'm very excited that rf strings support both regex style and format string. In the attached screenshot, behold how correctly varied correctColoring is. However, any dictionary or class inside of the {} in an rf string is not colored correctly. See how myDict['foo'] varies between incorrectDictionary and regularFString. The square brackets should be purple, and 'foo' orange, but instead it is all absorbed into red.

從這個 issue 中的 rf-string 範例開始，並將 myDict['foo'] 的醒目提示行為與一般 f-string 範例進行比較。檢視與 issue #186 中後續工作的相關實作，在 VSCode 中重現錯誤的著色，並在 rf-string 格式欄位中的 dictionary 或 class 運算式能夠一致地醒目提示時，視為該 issue 已完成。
