This commit completely removes the iostreams.NewColorScheme() initializer function in favor of exporting the type fields for greater clarity in its use.
The result being code specifying only the fields that matter to test cases.
This commit implements the actual changes around configuration setting / environment variable logic for displaying labels using their RGB hex color code in terminals with truecolor support.
One of the subtler changes in this commit is renaming generic ColorScheme.HexToRGB logic to render truecolor to ColorScheme.Label as this feature was being used exclusively for labels. This is due to confusion about introducing the new `color_labels` config on top of generic coloring logic.
This commit covers testing around the new ColorScheme.Muted logic based on various situations to gain confidence we get the accessible colors expected when enabled.
Additionally, this commit includes a small change to the existing 8-bit color logic to standardize on the same reset sequence for testing purposes. Essentially, `ESC[m` and `ESC[0m` are equivalent but this inconsistency with our other libraries makes setting up tests a little extra confusing and difficult.
This commit is focused on incorporating cli/go-gh accessible colors configuration setting into GitHub CLI experience along with new color function to supersede ColorScheme.Gray and ColorScheme.Grayf.
Originally, I was considering having all use of ColorScheme.Gray and ColorScheme.Grayf fallback to the new muted logic if accessible colors were enabled, however I decided not being that it exceeds the acceptance criteria. This means that every command using ColorScheme.Gray needs to be updated to use ColorScheme.Muted
This commit refactors the color format around table headers to ensure the GitHub CLI uses thematically appropriate colors based on dark background, light background, or no color at all.
In order to do so, `ColorScheme` needs information from the terminal about the background appearance (dark, light, none) to determine appropriate muted color.
This commit replaces `os.Setenv` with `t.Setenv` in tests. The
environment variable is automatically restored to its original value
when the test and all its subtests complete.

* Re-enable label colors for issue list
* Drop parentheses wrapping issue labels
* Support ANSI escape codes in TablePrinter cells
* Switch to a Truncate implementation that correctly measures ANSI escape codes
* Only output RGB color if terminal has truecolor capabilities
* Enable `ENABLE_VIRTUAL_TERMINAL_PROCESSING` on Windows - fixes wrapping issues with full lines and allows truecolor rendering
