Introduce Colab-like Forms in Notebooks

[indirivacua]

I would like to suggest implementing Colab-like Forms for Notebooks in VSCode. These forms can be used as input serializers, providing a more aesthetically way to set the values to variables in a code cell.

Here is the reference from Google: https://colab.research.google.com/notebooks/forms.ipynb.

Colab forms work by rendering the content of a cell input using a top comment followed by a @title tag. indicating that the code cell should be interpreted as a form-like structure. Each customizable variable is designated with a comment containing the @param tag, followed by its corresponding argument or configuration enclosed in curly brackets. Also you can use the @markdown tag which allows the inclusion of Markdown-formatted text between each value.

Here's an example:

# @title Example of Colab Forms { display-mode: "form", run: "auto" }
# the run: "auto" config makes that after running this cell manually, it will auto-run if you change the selected value.

# @markdown ---
# @markdown ### Enter a text value:
text = 'value' # @param {type:"string"}
# @markdown ---
# @markdown ### Enter a number value:
number_input = 10.0 # @param {type:"number"}
# @markdown ---
# @markdown ### Enter an integer value:
integer_input = 10 # @param {type:"integer"}
# @markdown ---
# @markdown ### Check a boolean value:
boolean_checkbox = True # @param {type:"boolean"}
# @markdown ---
# @markdown ### Enter a date value:
date_input = '2018-03-22' # @param {type:"date"}
# @markdown ---
# @markdown ### Enter a raw value:
raw_input = None # @param {type:"raw"}
# @markdown ---
# @markdown ### Select a number within a range:
number_slider = 0 # @param {type:"slider", min:-1, max:1, step:0.1}
# @markdown ---
# @markdown ### Select a text value from a dropdown or enter a custom one:
text_and_dropdown = 'value' # @param ["1st option", "2nd option", "3rd option"] {allow-input: true}
# @markdown ---
