Errors in the mamba.csh file created by mamba shell init

[EvanFishbein]

I believe there are two errors in the mamba.csh file created by micromamba shell init script when using csh shell.

line 45:
set __exe_name = (${__exe_name}:q.)
should read
set __exe_name = (${__exe_name:q})
The :q modifer does not work as written and the . has no purpose

line 51:
echo "Error unknow MAMBA_EXE: "$MAMBA_EXE", filename must be mamba or micromamba" >&2
should read
echo "Error unknown MAMBA_EXE: "\"$MAMBA_EXE\"", filename must be mamba or micromamba" >&2
The version of csh I use does not allow escaping a double quote inside a double quoted string. Also there is a missing "n" in unknown
