[BUG] Specviz: plot Y axis labels are confusing (switch from e to g formatting)

[karlglazebrook]

Describe the bug The plot Y axis labels are truncated, meaning the values are not possible to discern, when they include exponential notation.

To Reproduce Steps to reproduce the behavior:

Run the notebook at https://github.com/spacetelescope/jwebbinar_prep/blob/main/jdat_session/Specutils_Webbinar_solutions.ipynb

Expected behavior Needs to show all digits of Y axis label exponent

Screenshots

I am not sure if they are truncated, rather than just rendering 1.0 as 1.0e+0. This formatting was implemented in #865.

For example:

>>> print(f"{1:0.1e}")
1.0e+00

[karlglazebrook]

Since e0 = 1 it should simply be omitted. Probably change to g format to switch automatically

Note if I see e+0 I then expect there to be a second digit, hence the report.
