Don't repeat names of procedures in descriptions

[Beliavsky]

Looking at https://stdlib.fortran-lang.org/lists/procedures.html, in most cases the descriptions do not repeat the name of the procedure. For example, the description for adjustl is "Left-adjust the character sequence represented by the string. The length of the character sequence remains unchanged." I think this is preferable.

In other cases, the description starts by repeating the name of the procedure, for example

"arange creates a one-dimensional array of the integer/real type with fixed-spaced values of given spacing, within a given interval."
"arg computes the phase angle in the interval (-π,π]."

To be concise and maintain a consistent style, I think the descriptions should be

"Creates a one-dimensional array of the integer/real type with fixed-spaced values of given spacing, within a given interval."
"Computes the phase angle in the interval (-π,π]."
