Make default width of sidebar match default width of components

[MarcSkovMadsen]

Panel: 0.11.3

Going through the Panel gallery and wrapping things in Templates I can see that the default sidebar width of 300px of Templates does not fit the default widget of Panel components.

An example is the stocks_plotly.ipynb example that looks like

when adding

pn.template.FastListTemplate(site="Panel", title="Plotly Stock Explorer", sidebar=[ticker, window], main=[row[1]]).servable();

The consequence is friction and more work for users. They have to specify a fixed width of 250px or set sizing_mode='responsive'.

Solution

Increase the default sidebar width of all templates to wrap fixed width widgets.
