Added Description Field for Secrets and Variables

[LaoQi]

Fixes #33484

Is there a standardized length limit for these texts in the project? Maybe we should define constants for these. For now, I've capped them all at 4096 characters

LGTM except #33526 (comment)

Screenshots are necessary.

I noticed that the data field also doesn't have a length restriction. I'll add a length constraint to it as well. For this field, I think a limit of 65536 would be appropriate, although we can truncate the display when showing it.
The input data is generally UTF-8 encoded, so I will use UTF-8 character counting.
eg:

const (
	VariableDataMaxLength        = 65536
	VariableDescriptionMaxLength = 4096
)
if utf8.RuneCountInString(data) > VariableDataMaxLength {
	data = string([]rune(data)[:VariableDataMaxLength])
}

if utf8.RuneCountInString(description) > VariableDescriptionMaxLength {
	description = string([]rune(description)[:VariableDescriptionMaxLength])
}

Any other suggestions?

I think the description should be moved under value because it's optional. And it's better to have 2 rows at least.

Does it refer only to the form, or does it also include the list? Perhaps it would be better to place the description in the list above.
