feat: add width and height parameter

[ru322]

I created a PR to add optional argument to the algo and code

Motivation

There was a need to align the height and width of algo or code when they are displayed next to each other.

This change allows for setting the width and height of these blocks, which helps in creating a more organized and visually appealing layout when aligning multiple elements.

Changes

• add width and height argument to the algo
• add width argument to the code
• default width and height is auto

Usage

algo

#algo(
  title: "Floyd-Warshall",
  parameters: ("V", "E", "w"),
  width: 80%,
  height: 50%

)[
  Let $"dist"[u,v] <- infinity$ for $u,v$ in $V$\
  For $(u,v)$ in $E$:#i\
    $"dist"[u,v] <- w(u,v)$ #comment[edge weights] #d\
  For $v$ in $V$:#i\
    $"dist"[v,v] <- 0$ #comment[base case] #d\
  \
  For $k <- 1$ to $|V|$:#i\
    For $i <- 1$ to $|V|$:#i\
      For $j <- 1$ to $|V|$:#i\
        #comment(inline: true)[if new path is shorter, reduce distance]\
        If $"dist"[i,j] > "dist"[i,k] + "dist"[k,j]$:#i\
          $"dist"[i,j] <- "dist"[i,k] + "dist"[k,j]$#d#d#d#d\
  \
  Return $"dist"$
]

code

#code(
  width: 80%
)[
  ```py
  def floyd_warshall(G):
    # let G be an adjacency matrix
    dist = G
    
    for k in range(len(G)):
      for i in range(len(G)):
        for j in range(len(G)):
          if dist[i][j] > dist[i][k] + dist[k][j]:
            dist[i][j] = dist[i][k] + dist[k][j]
    
    return dist
    ```
