Inconsistent captions

[kno10]

The ceur template currently uses at least three inconsistent caption styles.

• Figure captions
• Table captions have an extra \par that IMHO should be replaced with a colon:
  

  ceurart/tex/latex/ceurart/ceurart.cls

  Line 2325 in 045cd1d

  {\rightskip=0pt\sffamily\small\textbf{\color{scolor}#1}\par#2\par\vskip4pt }}

• Captions of extension packages such as the excellent algorithm2e are default

Test document:

\documentclass{ceurart}
\usepackage{algorithm2e}
\begin{document}
\copyrightyear{2021}\copyrightclause{Public domain}\conference{Conference}
\title{Paper Title}\author{An Author}
\begin{abstract}Abstact\end{abstract}
\maketitle
Article Text
\begin{figure} \caption{Figure caption} \end{figure}
\begin{table} \caption{table caption} \end{table}
\begin{algorithm}[t] \caption{algorithm2e caption} \end{algorithm}
\end{document}

Result:

In my opinion, all three captions should be formatted as the Figure caption above.
