hide_non_significant kwarg should be configurable

[JasonMendoza2008]

hide_non_significant optional kwarg was added to Annotator but wasn't made configurable. This PR aims at fixing this bug.

This worked:

from statannotations.Annotator import Annotator
import matplotlib.pyplot as plt
import seaborn as sns

sns.set(style="whitegrid")

df = sns.load_dataset("tips")

x = "day"
y = "total_bill"
order = ['Sun', 'Thur', 'Fri', 'Sat']
ax = sns.boxplot(data=df, x=x, y=y, order=order)
annot = Annotator(
    ax,
    [("Thur", "Fri"), ("Thur", "Sat"), ("Fri", "Sun")],
    data=df,
    x=x,
    y=y,
    order=order,
    hide_non_significant=False
)
annot.configure(test='Mann-Whitney', text_format='star', loc='outside', verbose=2)
annot.apply_test()
ax, test_results = annot.annotate()

# show with big margins
plt.subplots_adjust(top=0.80)
plt.show()

This did not but should:

from statannotations.Annotator import Annotator
import matplotlib.pyplot as plt
import seaborn as sns

sns.set(style="whitegrid")

df = sns.load_dataset("tips")

x = "day"
y = "total_bill"
order = ['Sun', 'Thur', 'Fri', 'Sat']
ax = sns.boxplot(data=df, x=x, y=y, order=order)
annot = Annotator(
    ax,
    [("Thur", "Fri"), ("Thur", "Sat"), ("Fri", "Sun")],
    data=df,
    x=x,
    y=y,
    order=order
)
annot.configure(test='Mann-Whitney', text_format='star', loc='outside', verbose=2, hide_non_significant=False)
annot.apply_test()
ax, test_results = annot.annotate()

# show with big margins
plt.subplots_adjust(top=0.80)
plt.show()

Both work after the PR.
Tests were passed on Python 3.11.1.

I squashed everything like suggested last time I made a PR.

Hello @JasonMendoza2008 ,
Thank you for the PR!
I'm sorry I didn't check this sooner. In fact, I discovered it when I tried to update the documentation and add an example, and I implemented it independently.
A few more changes were required as it shouldn't be an argument for Annotator's __init__ at all (because configuring once is also persistent if not updated), and there were no tests checking the parameter at all.
I'm finalizing it and shipping it in v0.6.0.
See you for the next one, I hope :)
