fix: Standardize width of footer

[sachinchauhan2889]

Fixes #5511

Short description of what this resolves:

On the public event pages the sidebar spacing is different to the footer left and right spacing. This PR matched the left and right spacing of footer with sidebar and social links widget of public event page.

The footer is having a grid of 4 column which is wrapped in a center aligned container.
I have removed the container and created a grid with 3 columns. the 2 side column are empty(to match space with side bar of public event page and right side twitter widget). the center column is a nested grid which contain all footer data(grid of footer and all four columns.).
now footer is matched with the public event page.

Changes proposed in this pull request:

• matched the left and right spacing of footer with public event page side bar.

Works for me.

[iamareebjamal]

Why is there a need of such drastic structural changes? Please make minimum changes necessary

[sachinchauhan2889]

@iamareebjamal sir, please have a look at changes done by me. i have already done minimum changes needed. I have removed the outer container and replace it with a Semantic UI Grid.
In github it is showing i have changed 117 lines but actually i have changed 2 line and add 3 lines. i have screenshot of VS Code diaplaying changes done by me. please have a look at this.

[sachinchauhan2889]

@iamareebjamal sir, have a look at this. There is no such drastic change in structure. Only outer centered aligner container is replaced with semantic ui grid and for matching left side bar and right twitter widget, 2 empty columns are added.
I think it is good approach for this problem.
Sir if you told to change, i will think for another solution.
I think it looks drastic because it is showing 117 added and 114 lines deleted. But i manipulated only 4-5 lines. Just look this please. Sir
