[FEATURE] Change default snippet for “mod” and add “abs” snippet

[Jeon-Hajun]

Description of the Problem

When I try to use the modular operation with "\bmod", it is converted into "\b||" instead. It seems that the absolute value snippet was mistakenly assigned to the "mod" trigger.

Description of the Solution

I suggest correcting the trigger for absolute value to "abs" and adding a proper snippet for "mod".

The relevant code is located at
obsidian-latex-suite/src/default_snippets.js, line 257:

    {trigger: "mod", replacement: "|$0|$1", options: "mA"},

I propose changing it to:

    {trigger: "mod", replacement: "$0 \\bmod  $1", options: "mA"},
    {trigger: "abs", replacement: "|$0|$1", options: "mA"},

This would clarify the triggers and make the snippets more intuitive for both modular arithmetic and absolute value.

Hi,

mod is also short for modulus, the length/magnitude of a complex number. For physics (the authors major) modulus is used more. I am not the author or a maintainer and you're still welcome to make a pr, this is just an explanation why mod is used like this. (This issue is also a duplicate but it doesn't matter that much)
